Door-to-door sales
Some door-to-door representatives may have limited experience and may want customers to decide quickly. A customer might sign before fully understanding system size, equipment, pricing, and long-term costs.

Understand the issue first
These three common situations may leave you realizing only after solar installation that the plan was not the right fit.
The issue is often not solar itself, but making a decision before fully understanding the roof, energy use, pricing, and contract.
Online advertising
Online ads sometimes use phrases such as “free solar” to attract attention, which can misleadingly suggest that the system has no cost. Eligibility, payment obligations, long-term costs, and risks still need to be understood through the specific proposal and contract.
Friend referrals
A friend's experience can be helpful, but their roof, household size, energy habits, budget, and future plans may be completely different from yours.
A plan that works for someone else may not work for you.
Every home is different
There is no single solar plan
that fits every home.
Bigger is not always better, and the lowest price is not always the best value. What matters is whether the plan fits your actual energy use, family plans, and long-term budget.

Mark
Mark provides residential solar and energy consulting for Bay Area homeowners, helping families compare PG&E usage, EV charging, roof conditions, battery goals, and long-term plans before choosing a system.
Mark’s role is to help clients analyze their energy use, understand different options, compare quotes, companies, and available plans, and design a system that better fits their household’s actual needs before they make a decision.
Mark believes clients should not sign a contract they do not fully understand under pressure. A good solar plan should begin with the household's real needs, not a sales target.
“My goal is not to get you to sign quickly. It is to help you see the full picture before you decide.”
Bay Area solar planning
What Bay Area homeowners should consider before going solar
High household usage, evening demand, EV charging, and constrained roof space can pull a design in different directions. The right starting point is detailed usage plus a realistic roof plan.

Reference current rules:
PG&E time-of-use rate plans · PG&E solar and renewable energy
Connect PG&E TOU usage to the design
PG&E residential time-of-use plans charge different prices by time period. Review the current plan and interval usage before deciding how much solar or storage to consider.
Forecast EV and electrification growth
A new EV, heat pump, or electric water heater can change annual and hourly demand. Include known additions before final sizing.
Use roof space carefully
Smaller roof planes, shade, fire setbacks, and orientation can reduce buildable area. Module layout and production assumptions should reflect the actual property.
Treat backup as a defined goal
Battery capacity should be tied to the circuits and duration the household wants to support, not a generic promise of whole-home backup.
Real experience
Professionalism is demonstrated, not claimed.
Experience comes from real client needs, real proposal comparisons, and real project processes.

Why this site exists
Why did I build this website?
Over the years, I have seen families sign contracts after a door-to-door visit, an online ad, or a friend's recommendation without fully understanding the proposal.
Some bought systems that were too large, others too small. Some paid too much, while others discovered after installation that the outcome did not match what they understood.
I kept thinking that if someone could explain the complicated issues and compare the choices before a client signs, many regrets might be avoided.
That is why I built this website: to help more families understand first, then decide.
Not to rush you into buying solar,
but to help you make a decision that fits you.

Mark and His Solar Projects

Bay Area solar FAQ
Questions homeowners often ask
Are all Bay Area homes served by PG&E?
Many are, but municipal utilities and different generation arrangements also exist. Confirm the provider and rate plan on the property’s bill.
How does PG&E TOU pricing affect solar?
It changes the value of electricity by time of day. A useful comparison looks at hourly usage, expected solar production, and how a battery would actually operate.
Can an EV materially change system size?
Yes. Annual miles, vehicle efficiency, charging location, and charging time should be included in the load forecast.
Do shaded roofs rule out solar?
Not automatically. Shade, usable area, orientation, and equipment layout need to be modeled before deciding whether a practical design is available.
