How SolPan's solar panel tiers compare
Last updated October 2026
Rather than make you pick through hundreds of panel models, SolPan offers three simplified tiers. They stand in for the range of panels available, so you can see how a higher-wattage panel changes the result on your roof.
| Tier | Nameplate power | What it represents |
|---|---|---|
| Budget | 300 W | A lower-cost, lower-output panel |
| Standard | 400 W | A typical mainstream panel |
| Premium | 440 W | A higher-output, higher-cost panel |
Why wattage matters
A panel's nameplate power is how much it produces under standard lab test conditions. SolPan places the same-sized panel for every tier, so a higher tier fits the same number of panels but makes more power from each one. Roof space is usually the limit, and a higher-output panel gets more electricity out of it, at a higher price.
When a higher tier is worth considering
- Limited roof space: a small or shaded roof can't hold many panels, so more output per panel can matter.
- Plenty of space: with room to spare, extra lower-cost panels can often deliver similar energy for less. Installers can compare the two options on your roof.
What the tiers don't capture
Real panels differ in more than wattage: how well they handle heat, how fast they lose output over the years, warranty length, appearance, and the installer behind them. SolPan's tiers are simplified stand-ins, and its production model treats panels as generic types, so the results won't reflect any one manufacturer's real-world performance. A quote from an installer will name specific panels and prices.
