You\u2019ve chosen to go solar. Congratulations \u2013 your roof is soon going to start paying for itself. But here\u2019s a tiny secret about solar energy that most people learn a little too late in life: A high-quality solar panel with low standard solar installation will perform worse than an average solar panel with quality solar installation. Yes. That\u2019s how important solar installation is.<\/p>\n\n\n\n
Solar panel installation is not just a matter of \u201cfit the panels and turn them on.\u201d There is a proper solar installation guide because taking tiny shortcuts in solar panel installation can lead to costly surprises down the line. So before your rooftop solar system <\/a>installation process even begins, here\u2019s a simple, slightly humorous checklist to ensure everything goes smoothly, safely, and shock-free. Let\u2019s begin.<\/p>\n\n\n\n <\/p>\n\n\n\n Your solar panels will be installed on your roof for 25 years. This means that the structure supporting your solar panels cannot be of \u201cchalega\u201d quality. Consider this: Would you place a heavy water tank on a weak stand? No. A good solar panel installation requires that the structure supporting the panels has:<\/p>\n\n\n\n \u2022 Appropriate thickness (2mm, 3mm, 5mm depending on the wind zone)<\/p>\n\n\n\n \u2022 Hot dip galvanization (to protect against rust)<\/p>\n\n\n\n \u2022 Use of stainless steel screws (SS-304 is preferred)<\/p>\n\n\n\n \u2022 Appropriate tilt and row spacing<\/p>\n\n\n\n But what exactly is \u201chot dip galvanization\u201d? It is the application of a thick layer of zinc to the metal structure to make it rust-resistant. Not just painted, mind you. Properly coated. Because if the structure rusts, your solar panels won\u2019t just fall off \u2013 but they will weaken over time.

In layman\u2019s terms, earthing provides a safe path for electricity to escape. When there\u2019s a fault or surge, the excess current goes into the earth, not your inverter. A good solar power system should have the following earthing:<\/p>\n\n\n\n \u2022 Separate earthing for DC side (panels) But what exactly is soil resistivity? It\u2019s a measure of your soil\u2019s ability to absorb electric current. If your soil doesn\u2019t conduct well, earthing won\u2019t be effective.<\/p>\n\n\n\n Let\u2019s break it down like this: Water poured into concrete won\u2019t be absorbed. Water poured into loose soil will be absorbed immediately. It\u2019s the same with this. Without earthing, one surge will ruin:<\/p>\n\n\n\n \u2022 Your inverter Earthing is not that impressive. But it protects everything.<\/p>\n\n\n\n Now, let\u2019s discuss two things that most homeowners hear during the installation process and forget quickly after: DCDB and ACDB. They have complicated-sounding names, but they\u2019re not.<\/p>\n\n\n\n DCDB (Direct Current Distribution Box) deals with the power coming from your solar panels. ACDB (Alternating Current Distribution Box) deals with the power going to your home or the grid. They\u2019re like traffic cops. Solar panels produce electricity. The inverter converts it. But DCDB and ACDB regulate and safeguard it.<\/p>\n\n\n\n In a good solar panel installation manual, you need to check these things:<\/p>\n\n\n\n \u2022 DCDB and ACDB are separate<\/p>\n\n\n\n \u2022 IP65 rating (which means it\u2019s dust and water-resistant)<\/p>\n\n\n\n \u2022 Proper MCB\/MCCB breakers<\/p>\n\n\n\n \u2022 Surge Protection Device (SPD)<\/p>\n\n\n\n \u2022 Lightning arrestor (if necessary)<\/p>\n\n\n\n \u2022 Copper busbars for correct current flow<\/p>\n\n\n\n But what is a Surge Protection Device (SPD)?<\/p>\n\n\n\n SPD safeguards your system from voltage spikes. When the grid has voltage fluctuations or a lightning strike occurs in the area, the SPD takes the hit before it reaches your inverter. Without it, your inverter takes the hit. And let me tell you, inverters are costly shock absorbers.<\/p>\n\n\n\n Learn More <\/strong>– Solar Panel Made in India<\/a><\/p>\n\n\n\n Solar cables are not very impressive to look at. But they are the ones that determine how much power will actually reach your home. In most cases of substandard solar power installations, power losses occur not because of the solar panels, but because of poor wiring.<\/p>\n\n\n\n A good solar power system should have:<\/p>\n\n\n\n \u2022 XLPE insulated solar cables<\/p>\n\n\n\n \u2022 UV-resistant wires (exposure to sunlight will damage low-quality wires)<\/p>\n\n\n\n \u2022 Appropriate DC voltage rating (660\/1000V or higher)<\/p>\n\n\n\n \u2022 Appropriate routing within RPVC pipes or GI trays<\/p>\n\n\n\n \u2022 Labeling and tagging<\/p>\n\n\n\n Now, let\u2019s break this down for you. If you produce 10 units of power but lose 1 unit because of poor wiring, that\u2019s 10% gone \u2013 silently. With poor wiring, you won\u2019t see any smoke. You won\u2019t hear any alarms. You\u2019ll just have slightly lower savings. And that\u2019s the scary part.<\/p>\n\n\n\n While solar panels are the heart, the inverter is the brain. Solar panels produce DC power. Your home consumes AC power. The inverter bridges the gap by converting DC power to AC power. An incorrect inverter selection may result in:<\/p>\n\n\n\n \u2022 Power losses Before solar panel installation, you need to check:<\/p>\n\n\n\n \u2022 Capacity according to your system size<\/p>\n\n\n\n \u2022 Efficiency of 97% or higher (for larger systems)<\/p>\n\n\n\n \u2022 Correct grid synchronization<\/p>\n\n\n\n \u2022 Monitoring facility available<\/p>\n\n\n\n \u2022 Compatibility with single-phase or three-phase systems<\/p>\n\n\n\n Now, let\u2019s explain the above statement in detail. If your home connection is single-phase and you have a three-phase inverter, it won\u2019t work properly. It\u2019s like purchasing a three-pin plug for a two-pin socket. It won\u2019t fit. New inverters also enable monitoring through mobile apps. You can track daily production, monthly savings, and performance on your mobile. These features keep you in control.<\/p>\n\n\n\n Read More<\/strong> – TOPCon Solar Panel with Advanced N-Type Technology<\/a><\/p>\n\n\n\n When it comes to system sizing, many homeowners consider: \u201cLet\u2019s install the largest system possible.\u201d That\u2019s not always the best idea.<\/p>\n\n\n\n The right solar installation should have:<\/p>\n\n\n\n \u2022 Load analysis If you install a system that is too large, you may run into limitations on net metering, and also may export power without reaping the proper benefits. If you install a system that is too small, you may cut down on savings and your payback period will increase. That\u2019s why proper sizing will give you faster ROI.<\/p>\n\n\n\n Solar panels require direct sunlight. Even partial shading can significantly affect the output. Before installing solar panels:<\/p>\n\n\n\n \u2022 Conduct shadow analysis Now, let\u2019s discuss why shadow analysis is important- <\/p>\n\n\n\n Solar panels are wired in series. If one panel in a string gets shaded, the entire string\u2019s output drops. The shadow of a single water tank can affect the output of several solar panels. That\u2019s why a good solar panel installation on the rooftop should take into account the shadows for the whole year, not just the day of installation. Sunlight is free, but shadows are costly.<\/p>\n\n\n\nBefore You Install Solar: 8 Things You Must Get Right<\/strong><\/h2>\n\n\n\n
