Factors that Affect Solar Panel Costs in Alum Rock
For many Alum Rock homeowners, the decision to go solar depends on cost. However, the range of solar installation costs can be quite wide in Alum Rock, with typical prices between $20,000 to $40,000. There are numerous factors that greatly influence the price you’ll pay, which we'll go over below.
Solar Equipment
The size of the solar energy system you need, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by about $3,470. Some solar panel brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer higher efficiency. In a city like Alum Rock, 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 a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.
Solar Financing Terms
For some homeowners, paying for solar panels out of pocket can be financially overwhelming. Solar loans are offered by most installers in Alum Rock, which can lower, or in some cases eliminate, your upfront costs to make solar more affordable.However, the interest on solar loans also increases your total costs, so it’s important to take that into consideration as well. You can always lower the total you pay in interest and possibly even your APR by making a larger down payment.
Solar Panel Installation Company
A final consideration when trying to estimate the cost of solar for your home or business in Alum Rock is the company you choose to install your PV system. As with choosing a company to build a deck or pool, for example, you’ll have no shortage of solar installers that provide a range of services for different budgets.Larger national companies usually have lower costs, but some local companies compete with them by offering sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or extra services like electric vehicle charger installation, they might be cheaper overall.
