“NationPro USA uses an online-only model to remove sales commissions, typically lowering costs by 20–30% compared to local door-to-door installers.”
The Old Way (NEM 2.0): You sold extra power to the utility at full retail price. The grid was your “battery.”
The New Way (NEM 3.0): “Under the current Net Billing Tariff, the credit you receive for sending power back to the grid has dropped by roughly 75%. This means the goal of solar in California is no longer ‘exporting power’—it is self-consumption.”
At NationPro USA, we’re not just installing solar panels — we’re giving homeowners across the U.S. a better way to go solar. No sales pressure. No guesswork. Just remote quotes, licensed installers, and top-tier equipment delivered with speed and professionalism.
We combine cutting-edge design tools, local installation expertise, and national buying power to provide solar solutions that are affordable, efficient, and built to last.
“You are a PG&E, SCE, or SDG&E customer. Batteries allow you to store cheap solar power during the day and use it at night (when rates are highest), bypassing the low export rates of NEM 3.0.”
“You are an LADWP customer (which has different rules) or if your home uses almost all its energy during daylight hours.”
Your savings potential depends heavily on who provides your electricity. Select your utility below for a specific breakdown:
High rates, aggressive time-of-use plans.
Large territory, high peak rates.
Unique municipal rules, often better solar payback without batteries.
Highest rates in the state, making solar ROI very fast.

Yes. While NEM 3.0 changed the math, California’s electricity rates are some of the highest in the nation. Solar remains the most effective way to lock in a lower energy rate, especially when paired with storage.
By eliminating the in-home salesperson and their commission, online platforms like NationPro USA can often reduce the total system cost by $3,000 to $5,000 compared to traditional quotes.
The Federal Investment Tax Credit (ITC) allows you to deduct 30% of the cost of your solar and battery system from your federal taxes, provided you own the system (cash or loan).
Generally, no. California has an active property tax exclusion for solar energy systems, meaning the added value of the solar panels is not assessed for property taxes.
