What Our Clients Think

Yogesh Agrawal

Once they got going, it was very smooth, very professional, with predictable schedule. The panels went up quickly, in about 2-1/2 days, and the wiring etc was done in another day. PSE took their time to approve everything, but that's not Sphere's problem. The job looks nice, and I enjoy watching the panels' output on my laptop everyday! With an 8kW panel, I have seen consistent 40+ kWh of energy generation on sunny days in April, 2021. I highly recommend Sphere.

Frequently Asked Questions

Costs can vary anywhere between $20,000-40,000. This depends on a wide range of variables such as the size of your system, your energy requirements, the type of roof you have, and others. Contact us for a free and detailed estimate for your home.

You can claim a 30% Federal Tax Credit in Washington for the next ten years.

Net metering, provided by your state utility provider, offers the ability to sell any unused solar energy back to your utility provider at their same rate.

General factors that effect the efficacy of solar panels for your roof include direction (south-facing is best) and tree shading, but we can provide solar panels for homes under many circumstances.

The conditions that make our summers so enjoyable – long days and sunny weather – also lend themselves well to solar energy. In terms of annual solar production in the Northwest, 60% is usually generated during summer months, while about 20% is collected in the winter. Washington is not quite Arizona, though solar potential in this corner of the country is surprisingly strong. And if you need any further encouragement, look at Germany – the top ranked country in solar energy output despite the fact that it usually receives less sunlight than Western Washington.

Our solar panels and microinverters come with a 25 year manufacturer warranty.

We also back up our service and workmanship with a 10 year warranty

Monitor Your Solar Usage 24/7

Included with every installed system is a software program that allows end users to monitor on-site energy production and consumption. And if you wish to add further value, we can connect your solar array to a battery storage system or an electric car charging station.

10% of All Profits Are Donated to Sphere One

The founder of Sphere Solar Energy, Edwin Wanji, grew up in Kenya and saw first-hand how clean energy technology can drastically increase the prospects of marginalized communities. He started Sphere Solar Energy in order to give back to these communities. And he is committed to elevating their voices so that they are not only passive beneficiaries of the clean energy revolution, but also key contributors to its growth.

Sphere Solar Energy has executed four international projects since 2015.

Going forward, we will divide our resources between local projects and international projects that empower marginalized communities. All charitable work will be managed by Sphere One.
