Our PG&E bill went from over $2,000 to $160. You read that right.
We signed up with Senga last October. We have two EV’s and a house that can get VERY hot. Our PG&E bill went from over $2,000 to $160. You read that right, see the photo. If you are thinking about solar, talk to Senga. They’ll give you a clear and direct explaination of your options, no games or hassle like with other solar companies I’ve dealt with.

My wife and I are new arrivals to El Dorado Hills moving from San Jose in early summer of 2024. One of the first things we noticed in our EDH home was the price of energy! We knew we wanted solar because we previously had solar in SJ. We did as advised and after doing some research, we interviewed four different companies... we chose Senga Energy. Senga was honest about its pricing, kept us consistently informed as the solar purchase and install was taking place. The install went smoothly as well as all of the inspections and the final license to operate under PG&E. The install crew was great and the installation was very clean, easily passing our HOA review. We included a Tesla battery back-up system which should help our electricity bills and power our house in case of a black out. I would not hesitate in referring Senga Energy to our family and friends.I can't emphasize enough what a great experience we had! Kathy and Clark S./EDH
Read the full reviewVery helpful, responsive and transparent throughout the whole process.
We installed a full solar system with Senga Energy - solar panels on the roof, plus a home battery. They were very helpful, responsive and transparent throughout the whole process - we had lots of questions about the installation process, the financing, and permitting and approvals. Shane from Senga stayed with us throughout the whole process. The crew was very professional and communicated through all the steps including after approval from our utility to start up the system. Would highly recommend them to any homeowner considering solar.

Senga Energy was an absolute pleasure to work with from start to finish. Their team maintained excellent communication throughout every stage of the project—from the initial sales process and system design to permitting and installation. The professionalism displayed by Crew 5 during the installation is where everything truly came together. Although my family and I were on vacation during the install, Nick kept us informed every step of the way with regular text updates and photos, giving us complete confidence that the project was progressing smoothly. As a business owner myself, I pay close attention to how companies operate from beginning to end. Senga Energy exceeded my expectations in every aspect. Their team has built an outstanding operation centered on communication, professionalism, and quality workmanship. They should be extremely proud of what they’ve built, and I would highly recommend them to anyone considering solar.
Read the full reviewWe interviewed about 6 solar companies. Senga definitely helps to navigate with honesty and integrity.
Mason with SENGA was absolutely awesome. We interviewed about 6 solar companies and even entered a contract with another but when we allowed SENGA to review it, we found that they attempted to charge us more than what we had agreed to with the PPA. There is no one perfect solar solution in CA (lease, loan, PPA, etc) but SENGA definitely helps to navigate with honesty and integrity. Highly recommended.
Read the full reviewThe team worked like a well-oiled machine. They were very nitpicky about their work.
Senga solar installed our PV system. They always arrived on time and had the solar panels up on the roof. Most of the install was completed on the first day. The team worked like a well-oiled machine. All the workers got along great and worked very hard. They were very nitpicky about their work, and we’re very pleased with the outcome. They were absolutely great people to deal with.

Recognized nationally. Trusted locally.
We came out of commercial solar, where close enough is not an option, and brought that standard to family homes. Nine years and thousands of installs later, the people who design, permit and install your project are still Senga employees, and the number you call afterwards still rings in El Dorado Hills.
Service area
Headquartered on Golden Foothill Parkway and serving homeowners across the Gold Country and the Sacramento foothills. Same utility, same fire zones, same permitting offices, every week.
Not on the list? If you are in the Gold Country or greater Sacramento, ask. We probably already have a customer on your street.
Why homeowners choose Senga
Four things every Senga customer can count on, whether we are installing one battery or re-roofing the whole house.
The people on your roof and in your garage are Senga employees, trained and insured by us. One coordinator from the first call to the final inspection.
Production estimates, pricing and the true-up in plain English. If a project does not pencil for your home, we will tell you.
A 25-year full-system warranty on Solar-Based Utility systems, lifetime workmanship on roofs and double lifetime coverage on windows.
Service questions go to the same El Dorado Hills team that installed your system, not a national call center.
How it works
The same four steps for every project, with one coordinator the whole way.
We look at a year of your PG&E usage and your home, then walk through options at your kitchen table or on a call.
Week 1Layout, equipment, pricing and payment options in plain English. You decide, with no pressure.
Week 1 to 2Our in-house team manages the county, your HOA, rebates and PG&E interconnection where it applies.
Weeks 2 to 5Most installs take one to two days. We meet the inspector, turn you on and stay your single point of contact.

Still wondering about something? Call us. A real person in El Dorado Hills picks up.
Ask us anythingAlmost always. If you want backup power during outages or live in high fire-risk zones, a battery is worth it. Batteries are also best practice to ensure you store an adequate amount of energy to utilize after the sun goes down. This helps homeowners avoid pulling energy from your utility company.
An SBU lets you go solar with no upfront cost. We install and maintain a system - you just pay for the power it produces - at a much lower rate than PG&E.
1. If your roof is 10+ years old, consider replacing it first.
2. A new roof prevents costly rework later if leaks develop.
3. Roofing + solar bundles can qualify for better financing.
4. You’ll avoid having to pay to remove and reinstall panels.
5. Roof warranties are stronger when installed together.
Easy. A power purchase agreement transfers quickly and easily to the new homeowner through a simple agreement.
The install itself takes 1–2 days. Permitting takes 30–45 days, but we’re one of the fastest in the industry. Our in-house team handles all the paperwork and approvals for you.
1. Avoid a System Reclassification
Keep your original inverter and interconnection untouched if possible. Upgrading them could trigger a move to NEM
2. Use a Separate System
Add a new solar array with its own inverter and meter. This lets you preserve your NEM 1.0 or 2.0 agreement.
3. Add Battery Storage Instead
Batteries can offset your true-up costs without altering your solar export agreement — especially valuable under NEM 2.0.
4. Choose a NEM-Savvy Installer
Work with a contractor who understands utility rules and can structure the project to protect your grandfathered status.
5. Get a Utility Pre-Review
Have your installer submit an interconnection review to ensure your changes won’t forfeit your NEM rate plan.
