What is different about going solar in Walnut Creek
Summer cooling load
Walnut Creek is in the inland climate zone, with hot, dry summers. Solar production lines up with air conditioning, and a battery carries that savings into the evening.
MCE plus PG&E
Walnut Creek is in MCE's service area. MCE usually supplies your power and PG&E delivers it and handles the solar connection.
Permits
Walnut Creek is piloting SolarAPP+ for solar. We file through whichever path your project qualifies for and keep you posted.
Our work around Walnut Creek

Walnut Creek solar questions
Is solar worth it in Walnut Creek?
For many homes, yes, because summer cooling makes up a large part of the bill and solar produces most when it is hot and sunny. We run your numbers from your actual usage.
Should I add a battery with solar?
Under today's PG&E rules, a battery helps you use your own solar in the evening when power costs the most. Battery systems start from $15,000 installed, before rebates.
Do you install EV chargers in Walnut Creek?
Yes. We install Level 2 chargers and check whether your panel needs an upgrade or a load manager first.
Is Ally licensed for both solar and electrical work?
Yes. Ally Electric & Solar holds CSLB license #806465 with C-10 (electrical) and C-46 (solar) classifications. Our team has been licensed since 2002, and Ally has been in business since 2010.
