    In this video, I’m taking you through understanding how many solar panels to run a house off grid.

    We start by simplifying into three manageable steps: calculating your load, determining battery capacity, and sizing your solar panel array based on your location. Whether you’re pressed for time or here for the long haul, this video is packed with insights tailored for everyone.

    Ever wondered about the specifics, like the type of battery to use or how to calculate your actual sun hours? I dive deep into these questions, offering clear, actionable advice every step of the way. From determining the power usage of your appliances to understanding the nuances of battery efficiency, I’ve got you covered.

    I’ll walk you through how to calculate your daily energy needs, choose between lead-acid and lithium batteries, and determine the number of solar panels required to keep your lights on year-round. Understanding the impact of sun-hours on your solar setup is crucial.

    By the end of this video, the concept of: ‘how many solar panels do i need?’ will no longer be a mystery. Instead, you’ll be equipped with the knowledge to confidently plan and execute your solar project, no matter the size.

      I love watching these videos, and want to build a system but here in Scotland at 57N we probably need to change days of autonomy to weeks or even months…. blue sky days are so rare, seriously, depressing AF!!! Trapped on this prison island since Brexit too…😒🌧🌨❄

      Hello Sir, thank you for sharing your knowledge over here, I love it. Would you recommend some of the top websites and books for solar panels Techinicien to increase his or her knowledge ? Thank you

      I appreciate such straight forward approach…how about a little more on selection of inverters? Sizing inverter for the panels i may need to run whatever i am running.

      I’d like to have a solar system to just run my lights all leds so I think 20 lights shouldn’t use to much power and wouldn’t have to be that big,

      Hello. Can you do a video of a load analysis table which is already calculated in terms of watts and hours and all calculation done and gotten is 2,542 watt hrs. So i want you to show us if this 2,542 watt hrs if used in seven days on autonomous, on how to calculate the size of batteries in terms of volts and amperes, amount of solar watts and how many of them, charging controller to be used, fuses and dc mcbs and sizes of wires to be used?

      Hello sir, I have 8 gel 100ah batteries, 3 gel 200 ah batteries and 32 solar panels of 12volts 150watts, pliz help with the configuration, the controller I need plus the inverter I need, I'm in uganda 🇺🇬 we receive 9 to 11hrs of sunshine daily, and thank u sir for the teaching I appreciate

      Hi, thank you for sharing and making clear some points. I could be wrong on the battery capacity sizing your formula would not be: 6500 wh+(6500 wh*0.8* 1.25), 80%?

      If you provided content speaking like a human with personality… it’d be interesting… you sound more like a bot reading a script smh 🤦‍♂️

      Hello,

      To increase the profitability of your photovoltaic panel installation and maximize self-consumption, I've created the free application OptimElec, which lets you track and optimize your electricity production and consumption in real time.

      The application also displays the weather forecast for the next few days (cloud cover and solar radiation), enabling you to estimate your electricity production over the next few days.

      The application is available in English and French.

      I hope you find it useful!

      I only want to run a regular sized American fridge and a deep freeze freezer in my utility building. Planning a 48v system with one rack battery and six to 8 400w panels. Will that work?

      Its a simple calculation to work out what you need to go completely off the grid…. Estimate how much power you use per day…. estimate how much power you will produce in the middle of winter for say 2 months. Now figure out how many batteries you'll need to bridge that gap

      In a 10kw situation you covered this very well. However, 10kw is not the average if you have a heat pump HVAC, electric water heater and electric range. I get it that you just laid out a basic example but other electrical appliances were left out of the example. These other appliances are more common in the south and in addition sunlight is a better source of enegry in the south. My home is 100% electric. Daily electrical use would be closer to 30kw based on home size and how many appliances are in use. The below figures are more accurate based on the real electric consumption for the masses. My home use would be closer to 43kw per day. To actually send power back to the grid would require a daily surplus above my daily use. Such would require a system that creates more than my daily use. The cost to go off grid is very expensive. Just saying.

      Average kWh usage for 1,000 sq. ft home 32 kWh per day, 950 kWh per month

      Average kWh usage for 1,500 sq. ft home 37 kWh per day, 1,100 kWh per month

      Average kWh usage for 2,000 sq. ft home 43 kWh per day, 1,300 kWh per month

      Average kWh usage for 3,000 sq. ft home 67 kWh per day, 2,000 kWh per month
