Home Solar Designed for Backup, Safety & Long-Term Performance
FSP designs residential solar systems based on your actual load, backup requirement, roof condition, inverter capacity, battery capacity, surge load, safety, and future expansion. For most homes, we recommend hybrid systems with battery backup — unless you specifically need on-grid.
The Problem
Why Home Solar Often Disappoints
Load Shedding
Outages disrupt daily life — the real reason most homes want solar.
High Electricity Bill
Rising tariffs make monthly bills harder to control.
Wrong System Size
Package deals ignore your real load — over or undersized.
Weak Battery Planning
Undersized batteries die early and disappoint on backup.
Poor Inverter Selection
An inverter that can’t handle surge loads trips constantly.
No Safety Margin
No cloudy-day reserve — backup fails when you need it most.
No Roof Assessment
Capacity promised without ever seeing the roof.
No After-Sales Support
Installer vanishes after the sale — no service when it matters.

Design Factors
What FSP Checks Before Sizing Your Home System
A correct residential design depends on all of these — we do not skip any of them.
- Monthly electricity bill
- Monthly unit consumption
- Full load list
- Essential backup load
- Backup hour requirement
- Inverter capacity
- Battery capacity
- Solar panel capacity
- Roof space
- Roof type & condition
- Shadow condition
- Inverter & battery location
- Cable route
- Earthing & protection
- Cloudy-weather margin
- Future load growth
- Surge load (fridge, motor, pump, AC, compressor)
Load Priority
Not Every Load Belongs on Backup
A good hybrid system separates and prioritizes essential loads — connecting everything to backup wastes battery and money.
Essential Backup Loads
- Lights
- Fans
- Router / internet
- TV
- Refrigerator
- Selected sockets
- Security system
High-Power Loads
- Air conditioner
- Water pump
- Motor
- Heater
- Induction cooker
- Compressor
Battery & Safety Margin
How Your Backup Is Estimated
Backup depends on selected load, wattage, running hours, inverter efficiency, usable battery capacity, charging loss, cloudy weather, surge load, and future growth. Values below are editable placeholders, marked as estimates.
| Input | Your Value (editable) |
|---|---|
| Selected backup load | [X] W |
| Required backup hours | [X] hours |
| Inverter size | [X] kVA |
| Battery capacity | [X] kWh |
| Usable capacity | [X] kWh (after depth-of-discharge) |
| Estimated backup duration | ≈ [X] hours (estimate) |
| Safety margin | [X] % (cloudy-day reserve) |
| Future expansion note | [Headroom for load growth] |

Hybrid vs On-grid
Which Home System Fits You?
Hybrid Residential
- Includes battery
- Supports essential backup loads
- Suitable for load shedding
- Higher cost than on-grid
- Needs load priority planning
On-grid Residential
- Grid-connected, no battery by default
- Mainly for bill reduction
- No backup during grid failure
- Suitable where backup is not required
