Grass Valley’s sunshine is a real asset. The local weather station shows mean daily solar exposure of about 19.4 MJ/m², which is roughly 5.4 kWh/m² per day across the year.

Hot Water Rebates, Tariffs & Savings
For Grass Valley homeowners, hot water wa is becoming a talking point as people weigh up solar hot water vs electric hot water and even electric hot water vs gas hot water.

When you combine rebates with smart tariffs, timers or solar‑diversion, many homes can save hundreds of dollars a year and cut the payback period for a new energy efficient hot water system down to just a few years. Choosing the right mix of solar hot water vs electric hot water, or a carefully sized electric hot water system that runs mostly on your own solar, can be the difference between high bills and long‑term savings.
