Solar Heater for Cooking: Box, Parabolic and Panel Solar Cookers, How They Work, Temperature and Cooking Time, Indicative Rates, Best Foods, Limits and Safety in Pakistan
A solar heater for cooking is a solar cooker that uses sunlight to heat food, and in Pakistan's sunny climate it can save gas and fuel for slow cooking, boiling and baking. Prices run from about PKR 3,000 for a simple panel cooker to PKR 40,000 for a parabolic one. This page covers box, parabolic and panel solar cookers, how they work, temperature and cooking time, indicative rates, best foods, limits and safety.

- Panel cooker. Foldable reflectors around a pot, cheap and portable.
- Parabolic cooker. A dish that focuses sun on the pot, reaching 200 degrees or more.

How they work
A reflector or dish concentrates sunlight on a dark pot, and glass or a plastic bag traps the heat. Food cooks slowly and gently without fuel. Sun must be strong and unshaded, ideally between 10 in the morning and 3 in the afternoon.
Temperature and time
Box and panel cookers reach 100 to 160 degrees, enough for rice, lentils, vegetables and baking in two to four hours. Parabolic cookers are faster and can fry. Cooking time depends on the sun and the load.
Best foods
Rice, lentils, stews, vegetables, bread and cakes work well. Foods that need quick high heat, like chapatis on a griddle, suit parabolic cookers best. Use dark thin-walled pots with lids.
Limits
Solar cooking depends on weather and daylight, so it does not replace the stove entirely. It suits sunny months and slow cooking. Winter, cloud and smog slow it.
Safety
Reflected light can harm eyes, so wear sunglasses and avoid looking into the focus. Pots and glass get very hot, so use gloves. Keep children and pets away from parabolic cookers.
What to check before buying
- Type. Matches your cooking
- Sun exposure. Open, unshaded spot
- Pot. Dark and lidded
- Safety. Eye protection and gloves
Save fuel
Using a solar cooker even a few days a week saves gas or wood, and it is useful during gas shortages. Gas and electrical work on a geyser must be done by licensed tradespeople, with proper ventilation and earthing.
Before you decide
Choose the cooker for your food and sun, use dark pots and protect your eyes. A solar heater for cooking is a low-cost way to cook with free energy.
