Factors that Affect Solar Panel Costs in Rancho San Diego
For many Rancho San Diego homeowners, the decision to adopt solar energy rests on cost. However, the range of solar installation costs can be quite wide in Rancho San Diego, with typical prices between $20,000 to $40,000. There are a number of factors that significantly influence the price you’ll pay, which we'll go over below.
Solar Equipment
The cost of solar panels varies by thousands of dollars due to a few different factors. One of the major factors is the system size, which is measured in kilowatts (kW). Solar power systems that have higher efficiency or power production require better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $3,470.The kind of solar panels and equipment you want is another factor that will largely impact costs. Solar panels that are more efficient, like monocrystalline panels, tend to be more costly. Further, solar equipment consists of more than just the solar panels themselves. You’ll also need to decide on the kind of racks used to mount the panels, inverters, solar batteries, etc. It’s important to take all of this into consideration when searching for a solar system that’s in your budget.
Solar Financing Terms
If paying for solar panels in cash is too expensive, solar loans are an affordable option because they cut back your upfront costs and allow you to pay for your system over a term of, on average, between five and seven years.When estimating your overall cost, you should also calculate the interest you’ll pay if you opt for a solar loan. Also, paying more upfront can reduce the total interest paid over time.
Solar Panel Installation Company
A final factor to keep in mind when trying to figure out the cost of solar for your home or business in Rancho San Diego is the company you choose to install your solar system. As with choosing a company to build a deck or pool, for instance, you’ll have many options for solar installers that offer a range of services at different price points.Larger national companies usually have lower costs, but some local companies compete with them by promoting sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or add-on services like electric car charger installation, they might be cheaper overall.
