Is It Necessary to Clean Solar Panels?

After solar panel installation in your home, you are left wondering how to make the most out of your investment. The ideal way is to make sure that your solar panels have supportive conditions for generating electricity. This can be done by making sure your solar panels are clean. Clean panels increase the efficiency of the system and also the system’s lifespan. Continue reading

CA’s Solar and Natural Gas Ban Mandates Now in Effect: What You Need to Know

If you are building a California home this year, it will have to produce more clean energy — and in some places use more electric appliances — than ever before. A first-in-the-nation law requiring new homes to have rooftop solar panels took effect Jan. 1. State building codes also require better insulation and air filtration for new homes, and homeowners get additional incentives to install batteries to store solar power. Continue reading

How California’s New Solar Mandate Will Affect Homeowners

In 2018, the California Building Standards Commission approved a mandate requiring all new homes under three stories in the state of California to install solar panels. This solar roof mandate, which is the first of its kind in the United States, will go into effect on January 1, 2020. Continue reading

Solar Rebates and Tax Credits
California is far and away the most mature residential solar market in the country, which can be both a blessing and a curse in some ways. Overall, it is definitely a net positive for homeowners who live here because they are usually more informed about the intricacies of solar and the state’s solar lobby is powerful enough to fight for important savings tool such as net metering.

But the downside of the mature market is that, unlike other states like Massachusetts and South Carolina, where rebates and energy credits are used to incentivize homeowners to consider solar, California has discontinued almost all of its state-specific solar incentives because the industry is strong enough to sustain itself.

New California Energy Standards Effective January 1, 2017

code-changesEvery three years, the California Energy Commission (CEC) revisits its energy efficiency standards, augmenting the building code to align with recent technological advancements and the state’s new efficiency goals. The commission underwent this process again this year, identifying areas for improvement in both new construction and retrofits for residential and nonresidential properties.

With this most recent set of revisions, the commission is striving toward a pair of new state efficiency targets: achieving net zero energy for new residential construction by 2020 and for new commercial construction by 2030. Referred to as the 2016 version, these standards will go into effect January 1, 2017. Continue reading

Sun Control and Shading Devices

fh150jad_cropped_house copyThere are many reasons to control the amount of sunlight admitted into a building. In warm, sunny climates excess solar gain will result in overheating, in cold and temperate climates winter sun entering south-facing windows can contribute to passive solar heating, and in any event controlling and diffusing natural illumination will improve daylighting.

Selecting the Size of Your Solar PV System

Whether your goal is to generate your own clean energy, increase your home’s appraisal value, save money on your electric bill, or all of the above—investing in a small-scale solar electric system is a wise decision. A small solar electric system—or distributed generation (DG)—can produce reliable, emission-free energy for your home or business. However, it is important to make sure that your solar photovoltaic (PV) system is correctly sized, sited, installed and maintained, in order to maximize your energy performance. Continue reading
