Community Solar is a different model for solar energy. Instead of putting a solar array on an individual home, which requires home ownership, the right sunny location, a load bearing roof and fairly large upfront investment, Community Solar brings together a group of participants to build one larger solar array.

Production Snapshot


Community Solar


After an overwhelming interest in Community Solar, PUD 1 has decided to move forward with project here at the PUD warehouse . The location was chosen for its solar exposure, visibility and cost-effective proximity to existing electrical infrastructure. The arrays are slated to begin generating electricity to the PUD 1 electric grid before the end of June 2016, and owners will receive state production incentives and energy generation credits on their bills based on the number of shares purchased.

‚ÄčAll electric customers of PUD 1 are eligible to purchase a piece of the Community Solar project. Based on demand, we will likely have a randomized lottery selection of registrants to determine who will participate. Registration will be open from March 1st through noon on March 31st. The units are $100 each and there is a limit to 10 units per participant.

For the life of the solar projects (estimated to be 20 years) participants will receive an annual bill credit for the percentage of energy generated. Through the year 2020, participants will also receive a generous Washington State Production Incentive specifically for Community Solar, which is double the incentive for personal systems on a single home.

Community Solar Payback Calculator


The Community Solar Payback Calculator is intended to assist Mason PUD 1 customers in making their decision to participate in Mason PUD 1's Community Solar project.

1. Based on existing incentives included in Washington State law set to expire June 30, 2020.

2. An energy investment's Simple Payback Period is the amount of time it will take to recover the initial investment in energy savings, dividing initial installed cost by the annual energy cost savings. While Simple Payback is easy to compute, its weakness is that it fails to factor in: the time value of money, inflation, project lifetime or operation. To take these factors into account, a more detailed Lifecycle Cost Analysis must be performed. Simple Payback is useful for making "ballpark" estimates of how long it will take to "recoup" an initial investment.

3. Estimated payback calculation is based on numerous assumptions including the capacity factor of the units, Washington State incentive, price per installed kW, no cost of financing, etc. There is no guarantee of the estimated payback period.

4. Estimated payback calculation does not take into account the Federal Investment Tax Credit or the taxability of the incentive payments for State or Federal purposes. Please consult your tax advisor.
