Solar Installation FAQ

28 straight answers about solar, batteries, HVAC, financing, and what to expect when you work with a local installer in California.

Cost & Financing

What solar actually costs in California, how financing works, and how the federal tax credit fits in.

How much does solar cost in Bakersfield and Kern County?

A typical 6–8 kW residential system runs $14,000–$22,000 before the 30% federal tax credit. After the credit, most homeowners land in the $10,000–$15,400 range. Battery storage adds roughly $9,000–$15,000 per battery depending on capacity and brand.

Do you offer $0 down and 0% APR financing?

Yes — we partner with multiple solar lenders, including $0 down and promotional 0% APR loans for qualifying credit. We’ll model cash, loan, and PACE side-by-side during your free estimate so you can pick the structure that fits your situation.

How does the 30% federal tax credit work in 2026?

The federal Residential Clean Energy Credit has historically offered a credit equal to a percentage of qualified solar costs. Eligibility, amount, and availability for systems placed in service in 2026 depend on current law and your individual tax situation. Always confirm with a qualified tax professional before factoring it into your budget.

Will my loan payment really be less than my old PG&E or SCE bill?

For most California homeowners, yes — that’s the whole point of $0 down financing. We design the system to match your usage, then size the loan so the monthly payment is below your average utility bill. You see the math in writing before you sign.

Are there California-specific rebates I should know about?

Yes. The Self-Generation Incentive Program (SGIP) provides rebates for battery storage, with the largest amounts going to high-fire-risk areas, medical-baseline customers, and low-income households. California also has a property-tax exclusion so adding solar doesn’t trigger a reassessment.

Process & Timeline

What to expect from quote to power-on — and exactly who handles which step.

How long does installation take from start to finish?

Most residential installs are 1–2 days on the roof. The full timeline from signed contract to producing power is typically 4–8 weeks. The bulk of that is permits and the utility’s Permission to Operate (PTO) — not the install itself.

Do you handle permits and HOA approvals?

Yes. Permits, HOA submittals, structural letters, and PG&E or SCE PTO paperwork are all included. You don’t fill out a single form. Our project manager owns every step.

What does your free estimate actually include?

An on-site (or virtual) assessment of your roof, electrical panel, and shading; pulling 12 months of utility data; a custom system design with production estimates; and a written quote with cash, loan, and PACE numbers side-by-side. No pressure to sign on the spot.

Do you subcontract installs to other crews?

No. Every install is performed by Discount Solar’s own employees. That’s why our workmanship warranty is something we can honor for the full 25-year life of the system.

What happens if my roof needs replacement later?

We use quick-disconnect mounting. If your roof needs replacement, panels can be removed, the roof re-done, and panels reinstalled. We coordinate directly with most local roofers and offer a discounted reinstall rate to our existing customers.

Solar Equipment

Panels, inverters, monitoring, and what a 25-year warranty actually covers.

What brand of panels and inverters do you install?

Tier-1 panels and inverters from manufacturers with strong financial backing — so a 25-year warranty actually means something in 2050. Specific models are matched to your roof and budget during the design phase. We can install string inverters or microinverters depending on shading and layout.

How long do solar panels last?

Panels carry 25-year manufacturer warranties and typically continue producing meaningful power for 30+ years. Production degrades roughly 0.4–0.5% per year — meaning a 25-year-old panel still produces around 87% of its day-one output.

Will solar work on my roof if it faces east or west?

Yes. South-facing roofs produce the most, but east- and west-facing arrays still produce 80–90% as much over the year. We model your specific roof during the design phase so the numbers reflect your actual home.

How much maintenance do solar panels need?

Very little. In Kern County, a once-a-year rinse to clear Central Valley dust and ag debris is usually enough. Panels have no moving parts. We provide a monitoring app so you’ll see immediately if production drops.

Will solar increase my home's value?

Yes. Lawrence Berkeley National Laboratory studies show owned solar systems add measurable resale value. California’s solar property-tax exclusion means that added value isn’t reassessed as a property-tax increase.

Battery Storage

How storage works under NEM 3.0, how long it powers your home, and whether you should add it now or later.

Is a battery worth it under NEM 3.0?

Much more so than under NEM 2.0. Daytime export credits dropped substantially, so storing your own solar to use during peak evening rates is now the single biggest factor in payback. Battery-paired systems consistently outperform solar-only under the new tariff.

How long can a battery power my home during an outage?

Depends on what you run. Essentials only (fridge, lights, internet, a few outlets) typically last 12–24 hours per battery. Whole-home backup with central AC needs more capacity — usually 2–3 batteries stacked together.

Can I add a battery to an existing solar system?

In most cases, yes. We support AC-coupled retrofits for most existing solar systems regardless of original installer. We inspect your inverter and main panel during the site survey to confirm compatibility.

Where do batteries get installed — inside or outside?

Both work. Most LFP batteries we install are rated for outdoor garage walls or exterior side-yard installation. We choose location based on temperature exposure (extreme Kern summer heat is a factor), code clearances, and cosmetics.

Are home batteries safe?

Modern lithium iron phosphate (LFP) chemistry is significantly safer than older NMC chemistry — far less prone to thermal runaway. The batteries we install meet UL 9540 safety certification with integrated fire and thermal management.

HVAC

Heat pumps, AC sizing, and how HVAC pairs with solar in the Central Valley.

Should I do solar and HVAC at the same time?

Often yes. Sizing solar to a more efficient HVAC system means a smaller, cheaper solar install — and bundling means one permit cycle, one crew, and bundled financing. We model both scenarios (combined vs. separate) so you can pick what fits.

Do heat pumps actually work in Bakersfield winters?

Yes. Central Valley winters are mild enough that modern variable-speed heat pumps handle heating efficiently without backup electric-resistance heat. They’re an excellent fit for our climate and dramatically out-perform older AC + furnace combos.

How much can a new heat pump cut my power bill?

A modern high-SEER heat pump replacing a 10+ year old AC and furnace typically cuts cooling costs by 30–50%. Pair that with solar and your hottest-month bill can drop by 80%+.

What HVAC rebates apply in California?

Federal IRA tax credits (up to $2,000 for qualifying heat pumps), California TECH Clean California heat-pump rebates, and utility-specific rebates from PG&E and SCE may all apply. We calculate what you qualify for and help file the paperwork.

Warranty & Service

What's covered, by whom, and what happens if something goes wrong.

What warranties come with my system?

25-year manufacturer warranty on panels, 10–25 year inverter warranties depending on model, 10-year battery warranties, and our own workmanship warranty on the install (mounting, conduit, roof penetrations, and labor). We walk through every warranty in writing before you sign.

Who do I call if something stops working?

Us — directly. As a local Bakersfield-based installer, we own the relationship for the life of the system. You won’t be bounced between a national sales arm and a regional installer.

Do you service systems installed by other companies?

Yes. We troubleshoot, repair, and add storage to systems installed by other companies — including ones whose original installer is no longer in business. Call us and we’ll quote a service visit.

What if my installer goes out of business?

We’ve been operating in Kern County for years and intend to be here for the full life of every system we install. Manufacturer warranties on panels, inverters, and batteries are also independently honored — they don’t depend on us.
