Powering Your Solar Projects

Plan Smarter Before You Buy Solar

Solar ShopSentry provides independent third-party review of solar plans, vendor quotes, installer proposals, and equipment lists. We help homeowners, RV owners, and DIY builders better understand the design, components, risks, missing details, and possible alternatives before they commit to a major solar purchase.

Solar project help for serious DIY builders.

Buying solar parts is easy. Designing a system that is safe, balanced, expandable, and worth the money is the harder part.

1

DIY Solar Planning

Review your goals, loads, roof space, battery needs, inverter size, solar array layout, and overall system direction before buying parts.

2

Solar Quote Review

Send vendor quotes, installer proposals, shopping carts, or equipment packages for review before you sign or spend.

3

Premium Component Guidance

Practical guidance on Victron Energy, LiFePO4 batteries, Tier-1 panels, MPPT controllers, fusing, monitoring, and clean system layouts.

4

RV, Off-Grid & Backup Power

Support for RV power, 48V systems, shore-power assist, battery banks, DC air conditioning, off-grid cabins, and backup systems.

Before you sign or spend.

Solar proposals can look impressive while still leaving out important details. We help review the plan before you commit.

What We Review

  • Solar panel sizing and layout
  • Battery capacity and voltage choice
  • Inverter size and compatibility
  • MPPT charge controller limits
  • 48V vs 12V or 24V system decisions
  • Fusing, disconnects, breakers, and cable sizing concepts

What You Can Send

  • Installer proposals
  • Vendor shopping carts
  • Battery and inverter quotes
  • RV solar upgrade estimates
  • Photos, sketches, diagrams, and measurements
  • Competing quotes you want compared

Component philosophy.

We are not here to push the cheapest kit in a box. Solar ShopSentry favors clean, serviceable systems built around equipment that makes electrical sense for the project.

V

Victron-Based Systems

Inverters, MPPT controllers, Cerbo GX monitoring, Lynx distribution, shunts, and system visibility.

B

LiFePO4 Battery Planning

Battery capacity, voltage choice, parallel battery layout, fusing, disconnects, and future expansion.

S

Solar Array Design

Panel fit, string voltage, MPPT matching, shading issues, roof layout, airflow, mounting concerns, and expansion options.

P

Practical Protection

Fuses, breakers, disconnects, wire sizing concepts, bus bars, monitoring, and service access.

Review fees before major solar spending.

A small review fee before a major solar purchase can help prevent expensive mistakes, weak component choices, missing details, or unrealistic expectations.

$

Solar Quote Review

Starting at $49

Review of one installer proposal, vendor quote, equipment package, or solar shopping cart before you sign or buy.

  • Major component review
  • Missing or weak details
  • Obvious compatibility concerns
  • Questions to ask the vendor or installer
$

DIY Project Review

Starting at $149

Practical review for homeowners, RV owners, and DIY builders planning a solar, battery, backup-power, or off-grid project.

  • Project goal review
  • Battery, inverter, panel, and MPPT sanity check
  • Missing items and design concerns
  • Plain-English direction before buying parts
$

Advanced System Review

Quoted individually

For larger RV, 48V, off-grid, Victron-based, backup-power, or multi-document projects that require a deeper review.

  • Multiple quotes or equipment lists
  • Battery bank and inverter matching
  • Solar array and charge controller review
  • Protection, monitoring, and serviceability concerns

Review fees depend on the number of documents, system complexity, and level of detail requested. Solar ShopSentry provides practical third-party review and planning support, not stamped engineering, permitting approval, or licensed electrical installation.

Early Solar Review Program

Solar ShopSentry is currently accepting early solar project and quote reviews. As real customer feedback comes in, we will share selected comments and example results here.

What Early Reviews May Help Identify

  • Missing details in solar quotes or equipment packages
  • Battery capacity that may not match the project goal
  • Inverter, battery, and charge-controller compatibility concerns
  • Unrealistic runtime or production expectations
  • Weak expansion planning
  • Missing disconnects, fusing, monitoring, or protection details

Real Feedback Coming Soon

Solar ShopSentry is new, but the review approach is built around practical project planning, component sanity checks, and plain-English guidance.

Early customers will help shape the service, pricing, report format, and review process.

Interested in being an early review customer? Send your quote, parts list, photos, or project goals and let us know what you are trying to accomplish.

Early Solar ShopSentry reviews are already helping customers make smarter solar decisions before they spend.

RV Solar Review

Davis T.

“Best $149 ever spent.”

Allen provided a detailed layout of our solar components and panel array for our rig. Having installed panels about three years ago, I thought harvesting more than 2,000 watts was impossible — but the system he designed is now bringing in nearly 3,000 watts. He showed us firsthand what top-tier panels can do.

Even better, he sourced REC HJT panels at 10% below the lowest price I could find anywhere. The Victron system has been a game-changer too — the app gives us complete visibility into everything happening with our setup. No guessing, no surprises.

Highly recommend. Thank you, Allen!
Cabin Solar Review

Josh A.

“It has been a real game changer.”

My wife and I have a cabin in Wisconsin, and after cutting down some dead spruce trees, a visiting friend suggested we look into solar so we could enjoy it year-round. That’s when we quickly realized we are not do-it-yourselfers when it comes to solar shopping.

My wife found an ad for Solar ShopSentry, and reaching out turned out to be the best move we made. For a small fee, they helped us design a modest starter system with room to expand — and provided links to discounted, high-end components, batteries, and panels.

After hiring a local electrician to handle the installation, we now have 120VAC power in the cabin, running a microwave, electric heater, and a small refrigerator. We find ourselves out there far more than we ever used to be.

Thank you all!
