Residential solar power systems have never been as effective or as affordable as they are now, and it’s only going to get better. Despite the efforts of certain coal-clinging conservatives, South San Francisco (and the rest of California) is well on its way to completely relying on renewable energy. In fact, during 2017 California was over producing solar power! As technology improves, many homes are adding battery storage to hold onto that excess for when the sun is down, especially after changes in time-of-use peak periods. The future of renewable energy of any type will center around the storage options produced by companies like Tesla, LG Chem, and Mercedes. Rather than selling your excess solar power for a meager 5-10 cents per kWh, many homeowners are opting to store their power for future use. That means that households on time-of-use billing, running your home on solar power during peak hours will save you around 50 cents per kWh. To date, batteries just haven’t been that economically viable, even with the SGIP rebates in place that provide up to $4,000 for a residential 10kWh battery solution, but they are getting there quick.
