Once you've replaced all energy-consuming appliances with modern ones, you might find yourself with more energy than you initially needed. Here are some ideas how to make good use of it:
1. Solar energy can come in handy in the garden. For example, you can run an automatic sprinkler system on solar energy to keep your plants watered.
2. Solar panel system pairs well with an electric vehicle. An electric car requires a lot of energy
, so it's hardly possible to charge it with extras. But something small like a scooter might just fit right in.
3. Sell unused electricity into the commercial grid. A special net metering program allows grid-tie system owners to pump the extras back into the grid and receive bonuses, such as Solar Renewable Energy Certificates (SRECs). These certificates can later be sold to utility companies.
4. Add another cold storage. If you have enough energy, it's possible to install a second fridge or freezer for supplies. You can also consider a heat storage: boiler or even a garden sauna.
Possibilities are endless and it becomes a real quest to come up with new ideas to use your extra solar energy.
