Why does California require new built houses to install solar energy systems with batteries?
There are a few reasons:
▪ Reduce reliance on fossil fuels and combat climate change: California has ambitious goals to reduce greenhouse gas emissions and solar energy is a clean and renewable energy source. By requiring solar panels, the state aims to decrease dependence on traditional power plants that rely on fossil fuels.
▪ Increase energy efficiency and lower electricity bills: Solar panels generate electricity directly from sunlight, reducing the need to purchase electricity from the grid. Batteries can store excess solar energy generated during the day for use at night, further reducing reliance on the grid and potentially lowering electricity bills.
▪ Prepare for the future: Battery storage is seen as a key technology for integrating more renewable energy sources into the grid. As California adds more solar and wind power, batteries can help to balance supply and demand, ensuring a reliable electricity grid.
▪ Set a national example: California is a trendsetter in environmental policy, and other states may follow suit with similar requirements in the future.
Here's a breakdown of the reasoning behind the inclusion of batteries:
▪ Without batteries, solar energy production is limited to daylight hours. Homes still need to draw power from the grid at night when solar panels aren't generating electricity. Batteries allow homeowners to use solar energy even when the sun isn't shining.
▪ Batteries can help to offset peak electricity demand charges. Electricity prices are often highest during peak demand periods, such as hot summer afternoons when air conditioners are running heavily. Batteries can be used to store solar energy during these times and then used to power the home, avoiding expensive peak demand charges.
▪ Batteries can improve grid stability. With more solar and wind power on the grid, there can be fluctuations in electricity supply. Batteries can help to smooth out these fluctuations, ensuring a more reliable electricity grid.
While the upfront cost of installing a solar energy system with batteries is higher than installing just solar panels, the long-term benefits of lower electricity bills and a more sustainable energy future are seen as significant advantages.
