Reduce grid purchases
Generating electricity on-site can reduce how much electricity you need to purchase from the grid, depending on system size and usage.

What is solar energy?
Solar energy is energy from sunlight. In a rooftop photovoltaic (PV) system, solar cells absorb sunlight and convert that energy into electrical power.
THE SIMPLE IDEA
Light becomes electricity.
PV cells create an electrical current when sunlight provides energy to semiconductor material. The DC electricity is then converted by an inverter into AC electricity used by most homes and businesses.

A BETTER QUESTION
Not “Do solar panels make electricity?” — but “How much can my roof produce?”
Generation depends on factors such as location, time of day, season, weather, available roof area and shading. That is why a final system size should be based on actual energy use and a site-specific assessment.

02 · HOW IT WORKS
From sunlight to the socket in five clear steps.
You do not need an electrical engineering degree to understand the basic energy flow.
01
Sunlight hits the PV cells
Sunlight provides energy to the semiconductor material in the solar cells.
02
DC electricity is produced
The PV array produces direct current, or DC electricity.
03
The inverter converts it
The inverter converts DC electricity into alternating current, or AC.
04
Your building uses the power
Solar electricity can serve your appliances and other electrical loads.
05
Extra power has a path
Depending on the system, surplus electricity may go to the grid or be stored in a battery.
PV modules

Protection
Metering
Battery optional
Good to know: a rooftop PV system is more than panels. Mounting, cabling, protection,
inverter, metering and—when applicable—battery storage all form part of the system design.
03 · WHY SOLAR?
Solar is an energy decision, not just a panel purchase.
For many users, the value comes from a combination of energy savings, resilience, cleaner electricity and better visibility into how a property uses power.
THINK IN 3 LAYERSMoney + energy +
environmentCheck all three before you decide on a system.
Use your roof productively
A suitable rooftop can become a long-term energy asset instead of simply being unused space.
Generate electricity without on-site combustion
PV generation produces electricity from sunlight without burning fuel at the point of generation.
Track performance
Modern inverters and monitoring tools can make system generation more visible, helping owners spot unusual changes.
Cleaner at the point of generationNo fuel combustion on the
rooftop
04 · SOLAR & THE ENVIRONMENT
Clean electricity does not mean “zero impact.” It means a different energy story.
Solar PV has manufacturing, transport and end-of-life impacts, but during operation it generates electricity without combustion. The overall climate benefit depends on what electricity the solar generation displaces and on the system’s full lifecycle.
OperationalNo combustion while generating PV electricity
LifecycleManufacturing has an energy and materials footprint
Long termPV modules are commonly designed for multi-decade service

05 · SOLAR SYSTEM TYPES
On-grid, off-grid or hybrid?
The right architecture depends on whether you prioritise grid interaction, energy independence, backup or a mix of these.
MOST GRID-DEPENDENT
On-grid
Connected to the public electricity grid. Solar power serves loads, and grid interaction handles periods when solar generation is lower than demand.
BACKUP / INDEPENDENCE
Off-grid
Designed without a connection to the public grid. Battery storage and careful system sizing become important parts of the design.
SOLAR + STORAGE
Hybrid
Combines solar, grid connection and battery storage so energy can be generated, stored and used through different operating conditions.
06 · CHOOSING A SYSTEM
Open SolarWala calculator
Do not start with a panel count. Start with your energy story.
The right plant size is shaped by actual consumption, roof area, shading, solar resource, system configuration and your goals.
01How much electricity do I use?Look at bills and daily usage
patterns.
02How much shadow-free roof is available?Area and shading can limit
practical capacity.
03When do I use electricity?Daytime and evening demand can affect
system choices.
04Do I need backup during outages?This may point you toward
battery-capable designs.
05What rules apply at my location?Grid connection and incentive
rules vary and can change.
07 · CAN I MANAGE MY SOLAR PLANT?
Yes—many owner tasks are simple. Electrical work should stay professional.
A homeowner can learn to monitor, observe and care for a solar system. Installation, grid connection, wiring changes and electrical fault work need the right qualified professionals and local compliance.
OWNER ROUTINE
Things you can learn to do
- Read daily / monthly generation from the monitoring app.
- Watch for unusual drops in output or persistent inverter alerts.
- Keep the visible module surface reasonably clean using safe methods and installer guidance.
- Check that vents and equipment areas remain clear and accessible.
- Keep your installation documents, warranties and service contacts together.
PROFESSIONAL
Things not to DIY
- Opening or repairing an inverter or electrical enclosure.
- Changing DC / AC wiring or protection hardware yourself.
- Working on live electrical circuits or grid-connected equipment.
- Climbing on a roof when conditions are unsafe or wet.
- Changing the approved grid connection or protection arrangement.
OWNER CHECKLIST
What a healthy solar routine looks like.
Good solar ownership is mostly about observation and consistency: monitor generation, notice changes, keep the installation area accessible and follow the maintenance schedule provided for your specific equipment.

10 · QUICK ANSWERS
Questions people ask before going solar.
Use these as a starting point. Final system design, grid connection and current incentive rules should always be confirmed for the user’s location.
Ask SolarWalaYes, PV systems can still generate electricity in cloudy conditions, but
output is usually lower because less sunlight reaches the modules.
A typical grid-connected rooftop PV system is designed to stop exporting power
during a grid outage for safety. Backup requires an appropriately designed battery / backup system.
Location, season, time of day, weather, shading, temperature, module
characteristics and system design can all influence output.
Owners can often perform safe, surface-level cleaning when conditions permit
and when the equipment instructions allow it. Avoid unsafe roof access, harsh tools and any electrical
work.
Start with actual electricity use, available shadow-free roof area and your
goals. A site-specific assessment should confirm the final design.
