Panel cost is probably 10-20% of a total install cost. What you're paying for is labour, inverter, cabling and metal mounting equipment. Mostly labour. If you're able to self install you can shave years off ROI.
- bluSCALE4 3y agoYeah, I was looking into this. Look like I can get most of the equipment for a 18kW system for roughly 15k.
- zbrozek 3y agoDIY install is great. It's really not hard and saves a huge amount of money.
- irrational 3y agoWhere can you purchase everything wholesale?
- simpsond 3y agoI got my equipment through a local wholesaler. I built a BOM using solardesigntool and submitted through them. The wholesaler called me and accommodated me as a DIYer. CED Greentech was the company.

- htag 3y agoLabour: Having people climb around roofs is dangerous, and people with dangerous work expect higher compensation. Inverter: Cost of materials, assembly, and QA. You want good stuff for the amount of current passing through. Cabling: Cabling is mostly materials in cost. Conductive metals are expensive. Metal Mounting: It's heavy, and requires lots of raw material and expensive equipment to create it.
