This can be found in your electricity bill. The electricity bill mentions the number of units consumed by you for the given period. For further estimation let us assume your average electricity consumption per month is 400 units.<\/li>\n\n\n\n<li><strong>Solar system size estimate: <\/strong>Depending on the electricity consumed by you, you will get an estimated <a href=\"https:\/\/en.wikipedia.org\/wiki\/Solar_System\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">solar system<\/a> size. If you consume an average of 400 units, installing a 3kW should offset your consumption from the grid. For installing the system you will require 250- 300 sq. ft of shadow-free space.<\/li>\n\n\n\n<li><strong>Cost of the solar system:&nbsp;<\/strong>The solar system\u2019s cost depends on its size. Having a larger solar system reduces the system costs per kW and generates a large amount of electricity resulting in faster payback. A&nbsp;<a href=\"https:\/\/sanskriticomputers.co.in\/freshdemos\/freyrold\/a-3kw-solar-plant-powers-naveens-home-in-bangalore\/\">3kW solar system<\/a>&nbsp;costs around \u20b999,190 with a subsidy in Telangana as of Feb 2021. Now let us see how many months or years this system can pay for itself or what its payback period of solar panels is.<\/li>\n\n\n\n<li><strong>Amount saved: <\/strong>Depending on the amount of sunlight or irradiation level of the sun, the solar system will generate electricity. On average, a 1kW system can generate 4 units of electricity per day. So, a 3kW system can generate 360 units in a month. Now on average if you consume 400 units, the solar system will supply 90% of your electricity. You just need to pay for the remaining 10% or 40 units to the electricity board. Assuming, grid tariff rates of Rs. 7\/-, you have to pay only Rs. 280 and your system generates electricity worth Rs. 2,520 every month. This means you save Rs. 30,240 every year.<\/li>\n\n\n\n<li><strong>Solar Payback period:&nbsp;<\/strong>As we worked out some averages above, the solar panel payback period for the assumed installation can also be calculated. If a 3kW system costs \u20b999,190 in Telangana and you save \u20b930240 every year then for the solar system to pay back itself it will take \u20b999,190 \/ \u20b930240 = 3.2 years.<\/li>\n<\/ul>\n\n\n\n<p>The payback calculated will vary with factors such as system size, cost, electricity generation &amp; consumption, etc. Today, solar is the only investment in the market that can give you a payback period of 2 to 3 years with assured returns. Other factors such as increasing grid electricity tariffs, availability of financial incentives, net-metering, and ease of installation with EPCs like <a href=\"https:\/\/sanskriticomputers.co.in\/freshdemos\/freyrold\/\">Freyr Energy<\/a> are urging many homeowners and businesses to choose Solar over traditional forms of energy.<\/p>\n\n\n<section id=\"faqs\" class=\"main_spacer bg_ter\">\n    <div class=\"container\">\n        <h2 class=\"sec_heading-award lh-1 m-0\">Frequently Asked Questions<\/h2>\n    <\/div>\n    <br><br>\n    <div class=\"container\">\n        <div class=\"mx-lg-auto\">\n            <div class=\"accordion accordion-flush removeAccCSS\" id=\"accordionFlushExample\">\n                <div class=\"accordion-item\">\n                            <h3 class=\"accordion-header\">\n                                <button class=\"accordion-button collapsed\" type=\"button\" data-bs-toggle=\"collapse\"\n                                    data-bs-target=\"#flush-collapse0\" aria-expanded=\"false\" aria-controls=\"flush-collapse0\">\n                                    What is the solar panel payback period?\n                                    <div class=\"plus\"><\/div>\n                                <\/button>\n                            <\/h3>\n                            <div id=\"flush-collapse0\" class=\"accordion-collapse collapse\" data-bs-parent=\"#accordionFlushExample\">\n                                <div class=\"accordion-body\"><p><span style=\"font-weight: 400;\">The time it takes to pay for the installation of solar panels through overall electricity bill reductions and other incentives is known as the <\/span>solar panel payback period<span style=\"font-weight: 400;\">.
