Solar Panels
Panels produce energy, but the roof area, shade, tilt, orientation, fire setbacks, structural condition, and module layout all matter.

Home Solar Kits Start With the House
A home solar kit is not a generic box. It must match the roof, the main panel, the utility meter, the homeowner’s loads, the backup goals, the battery plan, and the local permit path.
The homeowner question
What Do You Want the System to Do?
The best home solar design begins with purpose. Bill reduction, blackout backup, peak-rate protection, EV charging, and off-grid readiness are different jobs.
Many people start by asking how many panels they need. That question matters, but it comes after the house is understood. A small electric bill, a large electric bill, a pool pump, a heat pump, a future EV, a battery backup plan, and a weak utility service all change the answer.
SunKits.com treats the home as the starting point. The roof, electrical panel, utility rules, family habits, and emergency loads should guide the kit.

The Parts of a Real Home Solar Kit
A real system is a designed electrical project, not a shopping cart.
Racking & Roof Attachment
Racking must respect waterproofing, roof type, wind uplift, load paths, rafters, tile, shingles, flat roofs, and inspection requirements.
Hybrid Inverter
The inverter is the power brain. It manages solar, batteries, grid power, backup circuits, and system behavior during outages.
Battery Storage
Batteries must be sized for realistic runtime and installed with required clearances, protection, labeling, and safety review.
Critical Load Panel
Most homes should not expect every circuit to run during blackout. Critical loads help separate what matters most.
Permits & Utility Approval
Drawings, labels, equipment specs, inspections, interconnection, and utility approval are part of the project, not afterthoughts.
Home Solar Is Not a Plug-In Appliance
A home solar kit connects to serious electrical equipment. The project may involve roof penetrations, service equipment, rapid shutdown, batteries, transfer equipment, utility metering, grounding, labeling, and fire-code review.
SunKits.com is educational. Home solar and battery systems require proper design, permitting, utility approval, licensed installation, inspection, and code compliance.

Common mistake
Buying Panels Before Understanding the Main Panel
The home’s electrical service can decide what kind of solar kit is practical.
A homeowner may have a beautiful roof and still need electrical work before solar can be installed correctly. Main panel rating, bus rating, breaker space, service conductors, grounding, meter location, and utility requirements can all affect the final design.
A battery backup system adds another layer. Backup loads may need to be moved into a critical-load panel or managed by approved equipment.
Design goals
Different Homes Need Different Kits
“Home solar” can mean several different things. The right kit depends on the goal.
Bill Reduction
Designed to produce energy during the year and reduce purchased utility power. Batteries may or may not be included.
Peak-Rate Protection
Uses batteries and smart operation to reduce expensive late-afternoon and evening utility purchases.
Blackout Backup
Focuses on critical circuits: refrigerator, lights, internet, garage door, medical equipment, and selected outlets.
Future-Ready Home
Plans for EV charging, heat pumps, batteries, panel upgrades, and larger electrical loads over time.
Sizing reality
Panels Are Sized by Energy. Batteries Are Sized by Time.
A solar array answers one question: how much energy can the home make? A battery answers another: what can the home keep running when solar is low, rates are high, or the grid is out?
This is where many “kit” discussions become confusing. A big solar array does not automatically mean a long blackout runtime. A large battery does not automatically mean the home can run every load. Electric heaters, ovens, pool equipment, EV chargers, air conditioners, and pumps can drain battery power quickly.
Solar Sensei’s Home Rule
“Do not promise the whole house until you know what the whole house actually uses.”
- Measure or estimate the load.
- Separate critical circuits.
- Respect surge and motor loads.
- Plan the battery for realistic runtime.
- Check the permit and utility path before buying equipment.

A Better Way to Start
Look at the Bill
Annual kWh use, seasonal changes, rate schedule, and peak periods help define what solar is being asked to offset.
List the Loads
Identify pumps, HVAC, refrigerators, computers, medical equipment, EV chargers, freezers, lights, and other important circuits.
Inspect the Roof
Roof age, material, shade, structure, access, fire setbacks, and available area affect the solar layout.
Review the Electrical Panel
The main service, breaker space, bus rating, grounding, and meter location can determine what upgrades or designs are needed.
Choose Backup Loads
Decide what should run during outages. Whole-home backup and critical-load backup are very different designs.
Permit the System
Final drawings, equipment specs, labels, utility forms, inspections, and approvals make the project real.

Ask Better Questions Before Buying Equipment
Home solar equipment is too important to buy blindly. Start with the house, the bill, the load, the roof, and the electrical panel.
