How much power does a DIY solar system use?

This isn't our first rodeo - we have a similar install video of our much larger, more complicated DIY solar system - it has 10kw of solar, 28kwh of lithium battery storage, and 5000w of 120V AC power. We’ll be referring to this project a lot as it informed a lot of the decisions we’ve made for this system.

How much do solar panels cost?

They still have plenty of life left in them, and the cost savings can be so significant that even if they need to be replaced a few years earlier you're still getting a great deal. Solar panels don’t need to be fancy. We grabbed a pallet of 30 250w snail trail panels for $1000 - so $33 each.

How do you charge a solar power combiner?

Now let’s turn that solar power on. Go outside to the combiner box and flip the breaker on the inputs you’re using. Then go inside and turn on the 20amp Breaker. You’ll see both lights turn on in the DC Midnite SPD, and the charge controller will slowly ramp up until the full amount of power is coming in. Now you’re charging your battery!

How many volts does a solar panel add?

When connecting in series, you take the positive of the first panel and connect it to the negative of the second panel. Then the positive of the 2nd panel to the negative of the 3rd panel, and so on down the line. This means that each panel adds an additional 37 volts for a total of nearly 230 volts.
