Solar & Battery Installation

A system sized for your home, not a template.

We design around your actual usage, your roof, and your electricity provider — then build it to keep as much of your own power at home as possible. That’s what makes solar pay off in California now.

What’s included

Custom system designSized to your bills, roof, and shading — not a one-size package.
Permitting & interconnectionWe handle city permits, inspection, and utility approval.
Battery integrationStorage configured for peak-rate savings and backup power.
Monitoring setupTrack production from your phone from day one.

Our approach

Designed for how California pays for power now

Under the Net Billing Tariff, exported power earns only a few cents per kWh while the electricity you buy back costs many times more. So the goal isn’t to build the biggest array possible — it’s to build a system whose output you actually use.

That changes the design. We look at when you use power, not just how much. We size the array to your consumption pattern, then add storage so midday surplus carries you through the expensive evening window instead of being sold off cheap.

It also means we’ll tell you when a smaller system is the better buy. Oversizing a roof to chase an export credit that no longer exists is the most common way homeowners overspend on solar in 2026.

The process

From first call to powered up

01

Site assessment

We review 12 months of bills, measure your roof, and check shading, roof condition, and your existing electrical panel.

02

Design & proposal

You get a written proposal: equipment, layout, production estimate, price, and honest payback math — line by line.

03

Permits

We prepare plans and pull city permits, and submit your interconnection application to the utility.

04

Installation

Most residential installs take one to three days on site, depending on system size and whether a panel upgrade is involved.

05

Inspection & PTO

City inspection, then Permission to Operate from the utility. We manage the paperwork and the follow-up.

06

Switch on & support

Your system goes live, we walk you through monitoring, and we’re local if you ever need us.

What you get

Included in every installation

  • A production estimate based on your specific roof orientation, tilt, and shading — not a regional average
  • Equipment selected for your situation, with the reasoning explained rather than a brand pushed on you
  • Battery sizing based on what you want backed up and how you actually use power in the evening
  • All permitting, plan sets, city inspection coordination, and utility interconnection handled by us
  • Manufacturer warranties registered in your name, with documentation handed over at completion
  • Monitoring configured and explained, so you can spot a problem yourself if one ever appears

Common questions

Installation, answered

How long does installation take?

The on-site work is usually one to three days for a typical home. The full timeline — assessment, design, permitting, install, inspection, and utility Permission to Operate — more often runs several weeks to a few months, with permitting and utility approval being the slowest and least predictable parts.

Will my roof need work first?

Possibly. If your roof is near the end of its life, it’s far cheaper to reroof before panels go on than to remove and reinstall them later. We flag this during the assessment and coordinate the sequencing so you’re not paying twice.

Do I need an electrical panel upgrade too?

Sometimes. Older homes with 100-amp service often need more capacity to add solar, a battery, and EV charging safely. We check your existing panel during the assessment and tell you up front — it’s not an upsell we spring on you mid-project.

What about the federal tax credit?

The 30% federal residential credit (Section 25D) expired December 31, 2025 for purchased and loan-financed systems. Lease and PPA customers may still benefit indirectly, since the financing company can claim a commercial credit. We’ll walk you through what genuinely applies to your situation, with no wishful math.

Can I add a battery later instead?

Yes, though it’s usually cheaper to do it at the same time as your solar because the electrical work and permitting overlap. If budget means starting with panels alone, we’ll design the system so a battery can be added cleanly later.
