Should I Install Solar Panels on My Roof

Key factors to consider:

Sun Exposure

Ideally, your roof has unshaded, direct sun exposure for a majority of daylight hours – especially midday when irradiation is strongest. Limited sunlight will hamper solar output.

Roof Condition/Age

Solar panels typically last 25+ years. Installing them on an aging roof that needs replacement soon won’t maximize the investment. Newer roofs are ideal.

Roof Type

Pitched, sloped roofs are best suited for solar panel mounting. Flat roofs can work but require additional racking equipment.

Roof Space

Plan for 10-20 square meters of open roof space per 1 kilowatt of solar capacity. A 5 kW system needs about 100 m2.

Financial Payoff

If electricity rates are high and/or net metering incentives are favorable, solar bill savings can offset system costs in 5-7 years – your breakeven point.

For most Pakistani homeowners with adequate roof space, age and sun exposure, solar delivers an advantageous ROI.

How Much Does a Solar Energy System Really Cost

Upfront purchase and installation costs for a standard rooftop solar system in Pakistan typically range:

  • Small 1-2 kW system: Rs. 150,000 – Rs. 300,000
  • Medium 3-10 kW system: Rs. 450,000 – Rs. 1,500,000
  • Large 10-100 kW system: Rs. 1,500,000 – Rs. 15,000,000

This comes out to roughly Rs. 90-120 (~$0.50) per watt for a fully installed residential or commercial solar system. Cost scales down for larger capacity systems.

You can estimate your monthly electricity bill savings based on your typical usage, solar system size, and the net metering credits you’ll earn. Most homeowners break even within 5-7 years.

Financing options like solar leases or loans can offset upfront purchase costs in exchange for monthly payments, but increase total lifetime costs. Outright purchase yields best ROI.

Key Components of a Solar Panel System

While solar panels get the most attention, a complete PV system is made up of various parts working together:

Photovoltaic Cells – The Technology Making Solar Possible

The solar cells within panels directly convert sunlight into direct current (DC) electricity through the photovoltaic effect:

  1. Photons from sunlight hit the semiconductor material in the cell
  2. This excites electrons which start moving to produce an electric current
  3. The DC current is drawn off via positive and negative terminals on the cell
  4. Cells are wired together to produce higher voltages

Silicon is the most common material used in PV cells today. Monocrystalline silicon cells are the most efficient while polycrystalline and thin-film cells are lower cost options.

Inverters – Converting the Sun’s Energy into Usable Electricity

The DC output from solar panels cannot directly power AC appliances in your home. An inverter converts the DC electricity into usable 120/220V AC current that can be fed to your electrical system.

Solar inverters also play key roles like:

  • Maximizing power harvest from the panels
  • Monitoring PV system performance
  • Providing critical safety shutoff functions

Microinverters can optimize each panel’s output while central inverters aggregate energy from the entire array.

Racking, Wiring, and Other Parts Working in Unison

Additional components that make up a solar system include:

Racking: Securely mounts solar panels while allowing adjustable angles/positioning. Roof mounts bolt into roof joists while ground mounts are anchored piles.

Wiring: Transmits electricity between panels, inverters, electrical boxes, and your home’s breaker panel. Following electrical code is critical.

Disconnects and Breakers: Required safety components that allow isolation and shutdown of solar equipment for emergencies and maintenance.

Monitoring: Hardware and software that tracks solar power generation and consumption. Ensures system health.

Batteries: Large batteries store excess solar energy for usage when panels aren’t actively generating (at night, cloudy weather etc).

When properly designed and installed, these components create an efficient, high performance solar energy system.
