The final <\/span><span style=\"font-weight: 400;\">price of a solar panel for homes in Chennai<\/span><span style=\"font-weight: 400;\"> depends on your DISCOM charges, product variant opted for, panel type, inverter type, mounting structure height, type of after-sales service, savings guarantee, roof height, etc. <\/span><span style=\"font-weight: 400;\">Prices are subject to change. Additionally, when calculating savings, we have considered an annual tariff escalation of 3% and an annual degradation of 1%. The actual final savings from an on-grid solar power plant in Chennai depend on the types of solar panels you\u2019ve installed and their efficiency, intensity of sunlight your rooftop receives, orientation of the panels and tilt angle, the pollution level and weather conditions in your city, the temperature, shadow on the roof, impact of dirt\/dust, and how well you maintain your panels after installation.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For any further enquiries about solar installation in Chennai, you can <\/span><a href=\"https:\/\/www.solarsquare.in\/go-solar\"><b>book a free solar consultation call with SolarSquare<\/b><\/a><span style=\"font-weight: 400;\">.\u00a0<\/span><\/p>\n                <div id=\"solar-calc-blog-component\">\n                <section class='calculate-savings'>\n                    <div class=\"calc-header\">\n                        <h6 class=\"calc-title\">Calculate your savings<\/h6>\n                        <img decoding=\"async\" src=\"https:\/\/sse-website.s3.ap-south-1.amazonaws.com\/blog\/arrow_right.webp\" alt=\"arrow_icon\"\/>\n                    <\/div>\n                    <p class=\"calc-subtitle\">\n                        Forecast your savings with solar on your investment on the SolarSquare\u2019s plant\n                    <\/p>\n                <\/section>\n                <section class=\"solar-calc-form\">\n                    <form id=\"scalcPageFormComp\" class=\"scalc-form-submission\" novalidate=\"novalidate\" method=\"POST\" enctype=\"multipart\/form-data\">\n                        <div class=\"form-wrapper form-flex-box pincode-solar-calc\" style=\"padding-bottom:10px;\">\n                        <div class=\"pincode-form\">\n                            <label for=\"homes_pincode\" class=\"form-label-solar\">Pin code *<\/label>\n                            <input type=\"text\" class=\"form-input-solar\" id=\"homes_pincode\" name=\"pin\" aria-describedby=\"Pin code\" value=\"\" placeholder=\"Enter Pin Code\" \/>\n                            <!-- <small class=\"error-message-mobile text-danger d-none\">Please enter a valid pincode.<\/small> -->\n                            <div class=\"error-message-mobile invalid-pincode d-none\" style=\"font-size: 0.85rem;\">\n                                <img decoding=\"async\" src=\"http:\/\/sse-website.s3.ap-south-1.amazonaws.com\/blog\/error_outline.svg\" alt=\"Error outline\" style=\"padding: 0px;\"\/>\n                                <span class=\"error-pin-text\">Please enter a valid pincode.<\/span>\n                            <\/div>\n                            <div class=\"not-active-city d-none\">\n                                <img decoding=\"async\" src=\"https:\/\/sse-website.s3.ap-south-1.amazonaws.com\/blog\/Frame+1355873452.svg\" alt=\"City map\"\/>\n                                <div class=\"not-active-city-text\">\n                                    <div class=\"not-active-city-text-title\">Oh!

Who is eligible for the PM Surya Ghar yojana?<\/b><\/p><p>Ans. Indian citizens installing grid-connected solar systems at their homes are eligible for the PM Surya Ghar yojana if they choose made-in-India DCR solar panels, legally own the property where the installation will be done, have never received a solar subsidy for up to 3 kW before, and have a valid electricity connection in their name.<\/p><p><b>Q2. How many ACs can run on a 3 kW solar system?<\/b><\/p><p>Ans. A 3 kW solar system can run one single 1.5-ton air conditioner. If you want to run two ACs, a 3 kW solar system is not enough. You will need a 5 kW solar system for that.<\/p><p><b>Q3. How many solar panels are required for a 3 kW solar system?<\/b><\/p><p>Ans. It depends on the module capacity. For instance, it will require ~6 panels if you use 540-watt panels, but ~10 panels if the modules are 300Wp. Here\u2019s the simple formula you can use: Number of solar panels = System capacity (in watts) \u00f7 the module capacity (in watts)<\/p><p><b>Q4. What is the lifespan of a 3 kW solar panel?<\/b><\/p><p>Ans. A well-maintained solar panel has a long life of 25 years. With proper care, the system can work at ~80% efficiency even after 25 years.<\/p>","protected":false},"excerpt":{"rendered":"<p>The 3 kW solar panel price in Chennai with subsidy for on-grid solar systems is ~Rs. 1....","protected":false},"author":3,"featured_media":3447,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[2,5,3],"tags":[],"class_list":["post-4531","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-residential","category-solar-panel-pricing","category-general"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.9 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>What\u2019s the 3 kW Solar Panel Price in Chennai With Subsidy?
