Early guidance on whether a roof-mounted or ground-mounted system may be the better fit for your property.
Project Planning Notes
Key details about permitting, utility requirements, and complexity that can affect your final design and cost.
You’ve seen DIY solar kits online.
Here’s what’s actually different.
If you’ve been researching solar, you’ve probably seen DIY kit options — a box of panels, some hardware, and a basic manual. They’re marketed as the budget way to go solar yourself. But there’s a category most homeowners don’t know exists: the prosumer self-install package.
- Consumer-grade or off-brand components
- Generic sizing — not designed for your home
- No engineering or plan sets included
- You figure out permitting on your own
- Little to no installation support
- Low upfront cost — higher risk of expensive mistakes
- Professional-grade equipment — same as installers use
- Custom-designed for your home, usage, and utility
- Engineering and permit-ready plan sets included
- Permitting and utility interconnection support
- Step-by-step install guide + lifetime technical support
- Competitive with DIY kit cost — significantly more complete
A prosumer self-install solar package gives you professional-grade equipment and engineering at a cost that competes with basic DIY solar kits — because you’re doing the installation, not paying a contractor. Use the free estimator above to see what a properly sized system may cost for your home.
What affects the cost of a self-install solar kit?
The cost of a self-install solar kit depends on several factors — and the final number can vary significantly based on your home’s energy usage, the size of the system you need, and what type of equipment you’re working with.
System size is the biggest driver. A small 5 kW system for a modest home is going to look very different from a 12–15 kW system designed to fully offset a high-usage household or power an EV.
Beyond panels, the total cost of a solar kit includes the inverter, racking and mounting hardware, wiring, monitoring equipment, and potentially battery storage. The type of inverter alone — string, microinverter, or hybrid — can shift the project cost by thousands of dollars.
Permitting, engineering plan sets, and utility interconnection paperwork are also part of a complete project. Some DIY solar buyers are surprised to find these costs aren’t included — and end up paying separately or skipping them and running into inspection issues. A prosumer self-install package typically bundles equipment, engineering, plan sets, and support into a single price, making it easier to compare true costs.
| System size | Typical home | Est. kit cost |
|---|---|---|
| 5–6 kW | Small / low usage | $8,000–$13,000 |
| 8–10 kW | Average home | $14,000–$20,000 |
| 10–12 kW | Larger home / EV | $18,000–$26,000 |
| 12–15 kW+ | High usage / battery | $24,000–$35,000+ |
Ranges are estimates based on equipment costs only and do not include installation labor, permitting fees, or utility-specific requirements. Use the free estimator for a number based on your home.

solar kit cost & self-install solar
Answers to the questions homeowners ask most before getting a solar cost estimate.
Most self-install solar kits land between roughly $8,000 and $35,000 depending on system size, equipment, and whether you add battery storage. A typical home falls in the $14,000–$20,000 range before the 30% federal tax credit. The estimator above gives you a number sized to your actual usage.
A basic DIY kit is usually a box of generic components with little design or support. A prosumer self-install package uses professional-grade equipment, is custom-designed for your home, and includes engineering, permit-ready plan sets, interconnection guidance, and lifetime support — at a cost that competes with basic kits because you do the install.
Most homes need somewhere between 12 and 30 panels. The exact count depends on your electricity usage, roof or ground space, and how much of your bill you want to offset. The estimator recommends a panel count based on your monthly bill.
Yes — nearly all jurisdictions require an electrical and/or building permit plus a utility interconnection agreement. A complete self-install package includes permit-ready plan sets and walks you through the interconnection process so you don't have to figure it out alone.
Adding battery storage typically increases a project by around $8,000–$15,000 depending on capacity and how much backup you want. Batteries are optional — the estimator can show you pricing with and without storage.
Thousands of homeowners have. If you're comfortable with basic tools and following detailed instructions — and you hire a licensed electrician for the final connection where required — a self-install is very achievable. You also get step-by-step guides and technical support along the way.
The estimate is a strong starting point based on the information you provide, not a binding quote. For a precise number, request the free detailed report or talk to an advisor — they'll refine the design around your roof, utility, and goals.
