The product, without the guesswork
A clean roofline, specified for the actual home
The final equipment schedule belongs in the proposal. These are the public-safe facts OC Solar uses before a site-specific design confirms the exact module and warranty.
Module efficiency
≥ 20.5%
Tesla's current TSP-420 datasheet publishes module efficiency of at least 20.5% under Standard Test Conditions.

18 power zones
Tesla says its cascading-cell design divides each panel into 18 power zones to reduce major production drops when a qualified portion of the panel is shaded or dirty.

Low-profile
Tesla Panel Mount uses an all-black module with no visible clamps or rails, allowing the panels to sit close to the roof for a restrained rooftop presentation.
Source: Tesla Solar Panels overviewBest starting point
A sound existing roof
Panel solar is usually the practical Tesla path when the current roof has adequate remaining life. If a reroof is already planned, compare panels with Solar Roof before deciding.

Powerwall-ready design
Solar and home battery storage are sized together when evening energy use or outage backup is part of the goal. Storage is optional and designed for the home, not assumed.

25-year coverage
Tesla's June 2, 2026 warranty covers product defects for 25 years and warrants at least 98% of rated peak power after year one, followed by no more than 0.45% annual decline for the next 24 years. Exclusions and documentation requirements apply.

Choose the Tesla path that matches the roof
Tesla Solar Panels are not the answer for every home. They are a strong starting point in these common situations.
01
Your existing roof is serviceable
Use conventional panels when the roof does not need replacement and the goal is to add solar without rebuilding the roof surface.
02
Curb appeal matters
The all-black module and low-profile presentation suit homeowners who want a visually restrained array rather than a mixed-color rooftop layout.
03
You may add battery storage
Design solar and Powerwall together when evening load shifting or outage backup matters, while keeping the system sized to the home's actual usage.
Compare before you decide
