Storm Tips For Solar System Owners

storm tips for solar energy system owners Hawaii

The recent double-whammy threat of hurricane Iselle and Julio reminds us that Mother Nature can be unpredictable and that it’s important to prepare ourselves when in the face of oncoming menacing weather. Haleakala Solar has been in the solar industry in Hawaii for over 37 years, through many tropical storms and hurricanes, and near-misses. For the most part, the weather we experience in Hawaii is mild and pleasant; however, at times we experience tropical storms or even hurricanes which may bring hazardous conditions of heavy rains and destructive winds. In preparation for these storms, along with stocking up on supplies and securing loose items in the yard, it’s important to know some facts and get some tips as a solar PV system owner during severe weather.

Solar photovoltaic panels are attached to the roof securely and are meant to withstand gusty wind conditions of a category 2 hurricane. When winds begin to exceed 105 mph structural damage to homes and businesses may begin to occur. The systems installed by Haleakala Solar are rated to withstand winds of even greater capacity than the norm; however, with flying debris from these types of rip-roaring winds, damage to the panels may occur, such as cracked glass. In 37 years we have NEVER had a panel come loose.

Unless you have an off-grid system (not tied into the utility grid), you may turn off the PV system to prevent a power surge from the grid. We suggest that you isolate your PV system by turning off the PV disconnect and your PV breaker. This will help isolate and protect your PV system in the event of a power surge. Enphase Microinverters have integral surge protection, greater than most traditional inverters; however, if the surge has sufficient energy, the protection built into the microinverter can be exceeded, and the equipment can be damaged. It’s important to call your insurance company to confirm that your solar is indeed covered under your hurricane policy.

Once the high winds and heavy rains have passed, you may turn the PV system back on; however, if you suspect that damage has occurred, it is advisable to contact Haleakala Solar for a complete inspection of the PV system before powering up the system. If you find damage did occur to the PV panels, inverters or wires, DO NOT touch the paneling or wiring since you may get electrocuted.

If you DID NOT turn off the system and your area loses electricity, your PV system will turn itself off automatically. Be aware that the PV modules, even when turned off, can still hold electrical current. Once power has been restored, the PV system will turn itself on automatically. At this point, check your online monitoring system (if applicable) to check the electrical output of the system and make sure it is registering at normal levels.

We hope everyone stays safe during this hurricane season. If you have any other questions not covered by the above, please call us at our state-wide toll free number, 643-8000, or drop us a line by using our contact form, and we’ll be sure to give you the answers you seek.

New Electric Vehicle Charging Station on Maui

EV station Haleakala Solar MauiA new electric vehicle (EV) charging station is available for public use in the Kahului Minit Stop parking lot off Dairy Road.

Maui is currently home to over 450 plug-in electric vehicles, which represents a tripling of growth from the 150 EVs in 2012. However, with 110,000 to 120,000 gasoline-powered cars on the road, there’s certainly much room for improvement.

Haleakala Solar is proud to support the growing need for charging stations around the island. 46.3 million barrels of petroleum were imported for Hawaii’s total energy use over the past year. The transportation sector consumes about 60% of that petroleum, so the adoption of EVs will greatly help reduce our dependence on imported fossil fuels. Plus, as our energy grid gets powered by more renewable sources, the electric vehicle will become greener too!

Freedom From Dirty Energy

Freedom from Dirty Energy

Free·dom [free-duhm]
1. the state of being free or at liberty rather than in confinement or under physical restraint.
2. exemption from external control, interference, regulation, etc.
3. the power to determine action without restraint.

Freedom is something we often take for granted. One of the greatest benefits of living in America is the amount of freedom we have, something people in a lot of other countries do not have. In Hawaii, though, there is one type of freedom that most people aren’t aware of. The freedom to choose the way they power their homes.

For decades, the only way we could affordably bring electricity into our homes was through the electric company. All other ways were not only more expensive but usually inconvenient as well. Well, finally there is a way to power our homes that is not only easy, but due to incredible tax breaks, even more affordable than purchasing through the utility companies. Solar energy.

Solar hot water can take care of all your hot water needs (one of the biggest energy hogs) and solar photovoltaic (pv) can fill your electrical needs. You can even purchase energy storage systems to supply you with electricity when your pv system isn’t producing enough.

Take control of your life and cut back your usage of dirty, fossil fuels. Solar is not only clean, but will actually save you money in the long run and put YOU in control of how your energy is generated. Which is another type of freedom. The freedom to determine how much you will be paying for your electricity every month.

Ten Tips For Living Green

think green go green

TEN TIPS for Living Green

Here are some simple tips and ideas on how you can live more sustainably and save money at the same time.

  1. Use Energy Efficient Appliances

    The major appliances in your home- refrigerators, washer and dryers, dishwashers, etc. account for a large chunk of your monthly utility bill. We’re not saying to go out and get rid of all your appliances and buy new ones right now, but when the time comes they need replacing, it would be smart idea to consider purchasing energy efficient models. Some current energy-efficient refrigerators could actually use less than half the energy of a model that’s 12 years old or older.

  2. Unplug Your Charger

    It’s amazing the amount of devices, tools etc. we use today that need recharging. Smartphones, tablets, and portable tools are just a few. Once people are done charging their devices, often they will leave the charger plugged in the wall. Unfortunately, chargers keep pulling power whenever they’re plugged in and all that energy is wasted. Best thing to do? Unplug the charger from the socket when charging is done.

  3. Improve the Efficiency of Your Existing Water Heater

    Well, we debated putting this one on here, but in all honesty, it is one of the best ways to cut down your energy bill. Tankless and solar water heaters in of themselves are great, but simple changes to your existing setup can cut your energy bills by 25 percent or more. Reduce the temperature of your water heater to 120 degrees, wrap it in a water-heater insulating blanket and insulate the first 3 to 6 feet of hot and cold water pipes. These changes don’t take a lot of time or money, but could make a real difference in the energy you use.

  4. Compost

    Composting is a great way to turn food and lawn wastes into rich mulch. What’s great about this is the idea taking something that’s considered (literally) trash and turning it into something valuable. Here are a few tips on how to get started:

    • Find an area in your yard with bare earth to start your composting pile. Having your pile on open earth would allow worms and other beneficial organisms to aerate the compost.
    • Gather a pile of lawn and garden waste onto the bare area. Be sure to mix “brown” materials like leaves and shredded paper with “green materials such as grass clippings. Having both ensures better results.
    • Keep your compost pile damp but not wet. Moisten materials as you add them to your pile. This will help ensure your pile will not dry out which would slow down the process.
    • Do not compost meat, bones or fish scraps. Stick with food scraps and yard waste only.
    • Turning your pile as often as possbile helps to speed up the process. Aerating the pile in this way adds oxygen which helps the process to work better.
    • Cover the pile. You can use wood, plastic sheeting, old carpet for example. Covering helps retain moisture and heat, two elements essential for composting.
  5. Switch to CFL or LEDs

    CFL (compact flourescent lights) and LED (light-emitting diodes) use up to 80 percent less energy than incandescent light bulbs and can last up to 25 times longer. Out of the three LEDs are generally the most efficient and have the longest life span but also the most expensive.

  6. Get a High-Efficiency Showerhead

    You can lower your water heating cost by getting a high-efficiency showerhead. Doing this can save up to 3,000 gallons of water per year. This equates up $50 in energy costs and roughly 1,000 pounds of carbon dioxide per year. The showerheads are specially designed to conserve resources while still providing like a luxurious-feeling shower.

  7. Buy Local Produce

    Many communities have a local farmer’s market. They are usually fresher (fruits and vegetables shipped from outside the state and country can travel up to two weeks before it arrives in grocery stores. As a bonus they are often cheaper than produce found in stores and many are organically grown as well.

  8. Use Rechargeable Batteries

    It’s amazing how many AA batteries one might use in the home. From remote controls to flashlights to computer mice. I recently went around my home and found over 40 AA batteries being used. Rechargeable batteries are more expensive than their non-rechargeable counterparts, but last many, many times longer. Just remember to unplug the charger after the batteries are recharged.

  9. Install a Drip Irrigation System

    Like many of the other tips listed, this one requires an investment up front, but delivers savings over the long run. If you are out in your yard watering your plants on a regualar basis, not only will installing a drip system save on your water bill, but plants will do better with the consistent watering and you will save time as well.

  10. Develop Better Energy Saving Habits

    This is something that really doesn’t cost anything other than a little bit of effort. Turn off the lights when leaving a room. Turn off the computer when not in use. Take shorter hot showers. Turn off water when brushing or shaving. Developing good energy saving habits may not seem like a whole lot over the short run, but if enough people do it over the long haul, it could add up. More than anything, it’s about developing the right mindset in helping our environment.

Go Solar – Conserve Water

stream of water

You already know that solar power reduces your energy bill and our dependence on fossil fuels, but did you know that going solar also saves water?

Water is used throughout traditional energy production: to pump crude oil out of the ground, remove pollutants from power plant exhaust, generate steam that turns turbines, flush residue after fossil fuels are burned, and cool power plants. In fact, fossil-fuel-fired thermoelectric power plants consume over 500 billion liters, or more than 132 billion gallons, of fresh water per day in the United States alone.

“The most important use of water for electricity production is for cooling,” says Adam Schlosser, an author of the study and the assistant director for science research at MIT’s Joint Program on the Science and Policy of Global Change. “The benefit of renewables like wind or solar is that you don’t need to boil water for steam to spin the turbines, and then you don’t need water to cool the steam. That cooling process is removed, saving a lot of water.”

According to the EPA, each kilowatt-hour (kWh) of thermoelectric generation requires the withdrawal of about 25 gallons of water, however only an average of 2 gallons of water is actually lost to evaporation for each kWh consumed.

If the average residential meter in Hawaii uses 615 kWh per month, that’s 1,230 gallons of water used in addition to your normal water needs. That may not seem like a big deal since that water use doesn’t show up on your water bill, but water consumption is something we all need to be aware of now – before water scarcity becomes a problem here in Hawaii.

The Hawaii Water Conservation Plan written in February 2013 shows that “over 90 percent of the state’s drinking water comes from groundwater sources, while much of the water used for agricultural irrigation comes from surface water sources. It is estimated that public water systems supply approximately 205 million gallons per day (mgd) of potable water across the state. Water used for agricultural irrigation is estimated to be well over 350 million gallons per day. In some areas of the state, demand for water is approaching the sustainable limits of supply, and these demands are expected to increase in the future. In order to sustain and protect our water for future generations, we must strive to be as efficient as possible in all of our water uses.”

Normally, when folks think about going solar, they’re thinking about their wallets, not the environment. When they do think about saving the planet with their solar panels, they’re probably happy about the incredible amounts of carbon pollution they’ll be avoiding by switching to clean energy. But now, you can add conserving water as one more reason to go solar.

The Advantage of Enphase Microinverters

Enphase Microinverter M190

Inverters convert direct current (DC) electricity generated by solar panels into alternating current (AC). The alternating current is then fed into the electrical grid. There are, in general, two types of inverters used in most solar systems, “central” and “micro” inverters.

Microinverters have several advantages over central inverters. Microinverters are connected to each individual solar panel in the system. Central inverters combine all of the power from multiple solar panels in one central location. With microinverters, if one panel is defective or has coverage issues, such as dirt, shading or even slight orientation mismatch, it will not affect the rest of the panels. With central systems, if one panel has issues, it could alter the energy output of other panels, greatly reducing the effectiveness of the entire system.

The development of microinverters has greatly increased the efficiency of solar systems and the company on the leading edge of microinverter technology is Enphase. One of the main reasons Haleakala Solar uses Enphase microinverters is because of it’s reliability, specifically its robustly-engineered hardware, integral for withstanding harsh climates of Hawaii.

Haleakala Solar was recently featured in an article on the Enphase website. Check it out here.

The White House Goes Solar (Again)

Earlier this month, solar panels finally returned to the White House. The American-made photovoltaic system installed at the executive residence is able to generate 6.3 kilowatts of solar energy and is estimated to pay for itself in energy savings over the next eight years, as long as the next president doesn’t remove them.

This isn’t the first time solar energy has graced the White House. President Jimmy Carter installed 32 panels back in 1979, after an Arab oil embargo spiked fuel prices. In a time when being environmentally-friendly wasn’t popular, President Carter said the solar panels and hot water heater would “either be a curiosity, a museum piece, an example of a road not taken, or it can be just a small part of one of the greatest and most exciting adventures ever undertaken by the American people.” Unfortunately, President Ronald Reagan removed them in 1986 when the roof was resurfaced. It’s also worth mentioning that President George W. Bush had some PV installed on a maintenance building and the president’s cabana to heat water for the outdoor White House pool.

Along with the White House going solar, President Obama announced that over 300 organizations, both in the public and private sector, have made commitments to solar power and energy efficiency. These commitments will result in more than 850 megawatts of solar, enough to power nearly 130,000 homes, as well as reduced energy bills for more than 1 billion square feet of buildings.

Currently, a new American home or business goes solar every four minutes. If the American solar industry continues at its current pace, a PV system could be installed every minute and twenty seconds by 2016.

Hawaii Tells HECO To Cut Electric Costs, Allow More Solar

Hawaii News Now – KGMB and KHNL

On April 29, Governor Neil Abercrombie and the Hawaii Public Utilities Commission (PUC) issued four mandates ordering Hawaiian Electric Companies (HECO) to “aggressively pursue” reduced electricity costs and allow more customers access to solar photovoltaic systems.

HECO has four months to file action plans with the PUC, showing their progress towards aligning their business model with customers’ interests and the state’s energy goals.

The PUC felt they had to step in after observing that “the HECO Companies appear to lack movement to a sustainable business model to address technological advancements and increasing customer expectations.”

“The traditional utility structures need to adapt to meet these challenges and to transform to become the utility business model of the future,” said PUC Commissioner Lorraine Akiba.

“The time for talk has ended. The time for action is upon us,” said Gov. Abercrombie. “I want to make it clear that where the utility and its regulations are concerned that this is not a series of recommendations, but rather an invitation and a guide path to action.”

Hawaiian Electric Statement

HECO President and CEO Dick Rosenblum issued a statement that says:

“The PUC issued a comprehensive set of energy policies and guidelines. In this challenging, fast-changing energy environment, we welcome the PUC’s clear direction and roadmap. We’ve been working on many of these initiatives, and these directives confirm the energy policy priorities that will guide our strategies and implementation.

We have many of the building blocks already in place, including our grid modernization work, the initial phase of our smart grid project, and our progress in renewable energy – now at more than 18 percent. We’ve begun deactivating older fossil fuel plants, such as Honolulu Power Plant and others on Maui and Hawai‘i Island. And we’re taking other steps to lower costs to customers, such as use of low-cost liquefied natural gas as a transition fuel.

We understand the importance of moving quickly and see this as an unprecedented opportunity to move aggressively on a shared vision for the utility of the future and on our role in meeting the needs of our customers.

We look forward to working with the PUC and the Hawai‘i State Energy Office as we move forward to develop and execute these comprehensive plans.”
