With a grid-connected system, size is less important as the network provides power in case your photovoltaic system fails. Solar systems with a power of no more than a few hundred watts prove practical.
Search the Renewable Energy Incentives database for information and facts about discounts in your country. You should also read the network measurement guidelines where you live. This includes how much money you can earn to generate excess electricity.
However, you can also set up solar panels that can generate enough power for all your needs from a solar panel installation company in Redding. Review the amount of electrical energy you are using now, and then calculate what you could likely save by taking protective and efficient measures throughout your home.
This approach gives you a better understanding of how large the system needs to be built. You can make any size system you want even if you think it's not bigger. The scaled-down system reduces the cost of solar panels. Take efficiency measures first and then design a solar panel system.
Once you have a better understanding of the amount of solar energy you need to produce each month, you can determine the cost of solar panels. For example, if you conclude that you want a photovoltaic system that produces about 250 kWh per month, that is 3000 kWh per year.
It determines how to position the solar panel array correctly. If possible, the photovoltaic solar panels for your home will face south and will also be tilted at an angle roughly the same as the local latitude.
