Factors that Affect Solar Panel Costs in Diamond Springs
Cost is often one of the most important factors for homeowners considering investing in solar. There are a few key factors that will push your cost above or below the average in Diamond Springs: solar equipment and system size, financing options and the solar installation company you choose. We’ll cover each of these briefly below.
Solar Equipment
One of the most significant factors to consider when it comes to the cost of adopting solar energy is the size of the solar system, which is measured in kilowatts (kW). The more power your household uses, the larger your system will likely need to be. You can expect to pay about $3,470 per kilowatt in Diamond Springs.Some solar brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer higher efficiency. In a city like Diamond Springs, where sunlight is abundant, efficiency can quickly pay off. Also, if you have a small roof or you don’t have a lot of space for your panels, higher efficiency options will be more impactful. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.
Solar Financing Terms
Many homeowners find the average cost of solar in Diamond Springs to be prohibitively expensive, even if the investment pays off over time. Thankfully, nearly every solar installer in the area offers financing options. Solar loans drastically decrease upfront costs for most homeowners, but they also lead to a higher cost over time because of interest.Though solar loans make adopting solar energy more accessible for Diamond Springs homeowners, they can also raise the total you pay for your system due to interest. If you make a larger down payment, though, you can avoid paying as much in interest.
Solar Panel Installation Company
A final consideration when trying to estimate the cost of solar for your home or business in Diamond Springs is the company you choose to install your solar system. Similar to choosing a company to install new cabinets, for example, there are plenty of solar installers that provide a range of services for different budgets.You may come across national solar installers that have lower prices because of their bigger brand name and access to bulk prices, or you might see small, local installation companies offering deals or promotions to compete with those major players.
