Despite the cloudy weather in Washington, the state is still considered a leader in solar energy. It is a model for other states that are committed to exploring the various benefits of solar energy. Washington’s solar incentives and the availability of solar easements are some of the factors that make it a great place to go solar.

Solar panels for sale in Washington

Solar panels in Washington are reliable and cost-efficient energy generators for your home, business, RV or a boat. They work as long as there is daylight, aren’t afraid of winds, hail, snow or rain, and last for over 25 years.

The average size of a home PV installation in the US is 5-6 kW. A system of this capacity covers 80-100% energy needs of a medium house. Its cost may vary from $5,000 to $10,000, depending on the panels’ brand and incentives available. Since a solar system powers your appliances during the day, your energy bills reduce greatly. Overall, a PV installation brings in around $100 each month on average and thus pays for itself in 6-7 years. 

Solar energy is a great solution for boondockers and sailors as well. Since panels work everywhere, don’t need fuel, don’t smell and are silent, they start to replace gas generators, which traditionally were used to charge house batteries. Sometimes even one panel is enough for everything you have on your boat or RV. Generally, panels go on a trailer roof, and when it comes to marine installation, modules are fixed on a stern rail, deck or canvas.

Solar inverters for sale in Washington

Inverter is another necessary component of a solar panel system. The panels by nature produce direct current which can’t be used by most house appliances. That’s why an inverter converts DC to AC and sends it either into the grid or to your appliances.

Another functions that inverter perform include:

  • Interaction with the grid;
  • Arc fault prevention and protection;
  • Optimization of the solar array production;
  • System monitoring. 

Inverters can be grid-tied, off-grid or hybrid. While the names of the first two are self-explanatory, a hybrid inverter can be used both as a grid-tie or an off-grid one. In other words, you can pair it with a battery, and if a blackout happens, the inverter switches your house to battery support instead of shutting down.

Inverter is the most complicated part of a solar installation and it requires proper maintenance. For Washington residents, it is recommended to put an inverter in a cold dry place out of direct sunlight — the garage is the best option. To prolong its lifespan, wipe the dust off of it, clean air intake filters and check the screen for errors.

Should I buy or lease my solar panels?

When it comes to solar panels, there are various advantages to both leasing and buying your own panels. One of these is the tax benefits, as well as the long-term savings.

Although leasing solar panels may not be the most cost-effective option, it’s still a great way to reduce your energy consumption and increase your home’s solar power. It’s also a great alternative for people who don’t want to buy solar panels.

Should I buy or lease my solar panels?

If you’re not ready to commit to buying solar panels, but would like to participate in a community solar project, then this is a great alternative. Through a shared solar program, you and other participants can earn a portion of the power that the project produces.

The history of solar power in Washington D.C.

Although many states have already enacted their own solar policies, Washington DC’s first net metering program was only implemented in 2000. Since then, the city has implemented various other policies to make solar power more accessible to its residents.

Today, Washington D.C. is 39th in the country when it comes to solar energy generation. It is powered by over 65% of the city’s electricity generation. Over the past five years, the number of residential, commercial, and utility-scale solar installations has increased significantly.
