What is a solar calculator?A solar calculator helps you design solar power systems, estimate prices, and predict energy savings.It can quickly calculate different solar energy concerns, such as:Panel sizing and system pricingPower consumption estimatesEnergy output and capacityInstallation costsElectric bill savingsReturn on investmentPayback periods or break-even pointsSolar financingAnd moreOur solar calculator lets you easily see which solar option is best for you. The results give you an idea of the costs and potential savings.How to calculate solar power payback periodCustomers often use solar calculators to help them understand how a solar power system can lower their electric bills. The calculated savings let you estimate how many years it'll take to see a return on investment (ROI).In the solar energy industry, this is known as the payback period. ROI is likely a huge consideration when you're deciding on solar energy.Here's a simple way to calculate the payback period for solar power. Take the total system cost and divide it by the estimated annual savings on electricity costs.To calculate annual savings, subtract the new average electric bill from the average of the old bill and multiply it by 12 months.(Old Electric Bill - New Electric Bill) x 12 months = Annual Energy Cost SavingsExample:Say a solar power setup costs $10,000 all up. This new solar array can cut your electric bill in half from $200 to $100 a month, which adds up to $1,200 in yearly savings.($200 - $100) x 12 months = $1,200 in savings per yearTo get the estimated payback period, divide the $10,000 with the estimated annual energy savings of $1,200$10,000 ÷ $1,200 = 8.33 yearsThis sample solar power system will have paid for itself in about 8 years and 4 months. And it'll continue to save you money for many years to come.How to calculate solar power system sizeThe size of your solar power system should suit your specific requirements. Solar power calculators are invaluable tools for determining how big the solar panel array should be.This lets you know if it can reliably power essential electrical appliances, especially if the system is off-grid.There are many factors to consider when choosing a solar power system.
