About Tesla Energy / Tesla Solar Proposals
Tesla Solar offers solar panels and the Tesla Powerwall battery as an integrated ecosystem. Their proposals often emphasize the Tesla app for monitoring and the Powerwall for backup power. Tesla uses its own inverter hardware in newer installations, which affects serviceability and compatibility with third-party equipment.
Key Items to Review in a Tesla Energy / Tesla Solar Proposal
- Confirm whether the proposal includes a Tesla inverter or a third-party inverter — this affects future service options.
- Review Powerwall capacity and backup duration relative to your critical loads.
- Understand the Tesla app monitoring platform and what data is available.
- Check panel specifications — Tesla sources panels from multiple manufacturers.
- Verify local service availability for Tesla hardware in the Central Valley.
What Robbins Energy Reviews in Your Proposal
A solar proposal contains a lot of information. We help you understand what matters — and what to ask before signing.
System Size (kW)
Is the system sized correctly for your actual usage?
Estimated Annual Production
Do the production estimates match your roof's real sun exposure?
Solar Panel Manufacturer
What brand and efficiency rating are the panels?
Inverter Technology
String inverter, microinverters, or power optimizers — each has trade-offs.
Battery Options
Is battery storage included? What capacity and backup duration?
Warranty Coverage
Panel, inverter, and workmanship warranties vary significantly.
Monitoring Features
How will you track production and catch problems early?
Price Per Watt
The most useful apples-to-apples comparison across proposals.
Financing Terms
Cash, loan, or lease — each has different long-term implications.
Why a Second Opinion Makes Sense
Confirm System Sizing
An undersized system won't offset your bill. An oversized system costs more than necessary. Proper sizing depends on your actual 12-month usage, roof orientation, and shading.
Understand Production Estimates
Production estimates vary based on assumptions. We review the methodology and compare it against local irradiance data for your specific address.
Compare Equipment Options
Solar panels, inverters, and batteries vary in performance, warranty terms, and suitability for Central Valley conditions. We help you understand the equipment in your proposal and what options are available.
Review Long-Term Ownership Costs
Warranties, monitoring, and service availability matter over a 25-year system life. We help you understand what happens if something needs repair.

NEM 2.0 vs NEM 3.0 — What It Means for Your Proposal
NEM 2.0
Systems interconnected before April 15, 2023 are grandfathered on NEM 2.0 for 20 years. If you have an existing system, your export rate is protected.
NEM 3.0
New systems interconnected after April 15, 2023 are on NEM 3.0. Export rates are lower, which means battery storage has a stronger financial case.
Battery Storage Under NEM 3.0
With NEM 3.0, storing solar energy and using it during peak evening hours (4–9 PM) is more valuable than exporting it. A properly sized battery can significantly improve your system's economics.
Tesla Energy / Tesla Solar Solar Proposal — Frequently Asked Questions
Can Robbins Energy review my Tesla Solar proposal?
Yes. Robbins Energy provides a free review of Tesla Solar proposals, including system sizing, Powerwall specifications, inverter type, production estimates, and pricing.
Can Robbins Energy service an existing Tesla Solar system?
Yes. We service existing solar systems including Tesla Solar installations. We can diagnose performance issues, add battery storage, and perform maintenance regardless of the original installer.
What inverter does Tesla Solar use?
Newer Tesla Solar installations use the Tesla inverter, which is proprietary hardware. Older installations may use third-party inverters. The inverter type affects serviceability and compatibility with non-Tesla equipment.
Can I add a Tesla Powerwall to my existing solar system?
Tesla Powerwall compatibility depends on your existing inverter. Robbins Energy can evaluate your system and recommend whether a Powerwall or an alternative battery (such as Enphase IQ Battery or FranklinWH) is the better fit.
We Service Existing Solar Systems — Regardless of Installer
If you already have solar and need service, we can help — even if we did not install your system.
