Solar power is one of the most efficient and eco-friendly ways to generate electricity, and it’s becoming increasingly popular as the cost of solar panels continues to drop.

Solar loans are a great way to finance your solar panel installation. There are a few different types of solar loans, but they all work in essentially the same way: you borrow money to pay for the cost of your solar panel installation, and then you make monthly payments back to the lender over a period of time.

This solar loan calculator will help you determine the monthly payments and total interest you'll pay for a solar loan.

Understanding your solar loan calculator results

Monthly payment: This is how much you will pay toward your loan each month. It includes principal and interest repayment.

Total interest paid: The interest amount you’ll pay over the lifetime of the loan depends on the interest rate. Interest rates for solar loans usually range from 6% to 36%. Your credit score, income, existing debt, and other factors determine what interest rate you get. People with high credit scores and little debt often get the lowest interest rates.

Total principal paid: This is the original loan amount.

Total repaid: This is the amount you’ll pay by the end of the loan, which includes the loan principal and interest.

Benefits of a solar loan

The biggest benefit of solar loans is that they allow you to go solar with little or no money down. That means you can start saving on your electric bill from day one, and you don’t have to worry about coming up with a large upfront investment.

There are a few things to keep in mind when you’re considering a solar loan. First, make sure you understand the terms of the loan, including the interest rate and the length of the repayment period. Second, be sure to shop around and compare offers from different lenders to get the best deal. And finally, remember that going solar is a long-term investment, so make sure you’re comfortable with the monthly payments before you sign on the dotted line.

How much does solar cost?

Solar power is one of the most promising renewable energy sources available today. Solar photovoltaic (PV) technology converts sunlight into electricity, and offers a clean, emissions-free way to generate power. Solar PV systems have become increasingly affordable in recent years, making them a more viable option for homeowners and businesses looking to reduce their energy costs.

If you’re considering making the switch to solar, you’re probably wondering how much it will cost. The short answer is that the cost of residential solar has fallen dramatically in recent years, making it a very attractive option for homeowners.

The cost of solar panels has fallen by more than 70% over the last decade, making them a very affordable option for homeowners. The average cost of a 6 kilowatt (kW) system – enough to power a typical home – is now around $12,000 before rebates and incentives.

Factors that impact the price of your solar panels

However, the price you pay for your solar panels will vary depending on a number of factors, including:

  • The size of your system: Larger systems will obviously cost more than smaller ones. The average 6 kW system mentioned above would typically have around 20 panels installed.
  • Solar panel type: There are two main types of solar panels – monocrystalline and polycrystalline – with monocrystalline being slightly more efficient (and therefore more expensive).
  • Solar panel efficiency: This measures how well a panel converts sunlight into electricity and is typically between 15% and 20% for most panels on the market today. Higher efficiency panels will obviously cost more than lower efficiency ones.
  • Solar panel brand: There are hundreds of different brands selling solar panels, with prices varying significantly between them. It pays to shop around and compare prices before making a purchase.
  • Installation costs: The price you pay for installation will also vary depending on who you hire to do the job and where you live. In general, installation costs tend to be lower in states with strong solar incentives like California and Arizona.
  • Rebates and incentives: Many states offer rebates or tax credits when you install solar panels, which can significantly reduce the upfront cost. Be sure to check what’s available in your state before buying any panels.

Solar PV systems typically have payback periods of 5-10 years in most parts of the country. This means that the savings on your electricity bills will eventually cover the initial cost of installing the system. After the payback period, you will essentially be generating free electricity for many years to come! In some cases, it may even make financial sense to sell excess electricity generated by your system back to your utility company at a profit!
