Written by Eddie B. Robinson / Checked by Justin Tucker

best solar heat lamps

Raising chickens, pigs, reptiles, goats, and other livestock is a cinch if one has the best solar heat lamps to ensure a warm environment for optimal growth. These lighting fixtures are not only excellent for heating living spaces. They can also promote optimum plant development and save you money.

Picking the correct heat light is a straightforward process, as long as one knows what to look for. In this review and buying guide, we focused more on three crucial parameters.

  • Ability to Generate Heat: A light bulb’s heat-generating capabilities depend on its power. The higher the wattage rating, the greater its heat production. For example, a 60-watt incandescent bulb will always produce more heat than a 30-watt fixture.
  • Battery Capacity: Solar lights do not draw power from photovoltaic cells. Instead, they get it from rechargeable batteries. The larger the dry cell capacity (expressed in mAh), the longer the light bulb operates. This can also translate to more heat generation. For instance, a 2200mAh battery will run the lighting fixture longer than a 1200mAh dry cell.
  • Solar Panel Type: Monocrystalline photovoltaic cells are the gold standard of solar panels, ensuring a higher conversion rate with each sun exposure. Polycrystalline panels, which are durable and efficient options, come next. Thin-film solar panels are excellent for their flexibility. Unfortunately, they are the least efficient among the three solar panel types.

Other factors can play a role in one’s buying decision. One can check other parameters to look for in our comprehensive product reviews and consumer guide.

What Is A Solar Heat Lamp/ Who This Is For


Solar powered heat lamps are lighting fixtures used primarily for increasing ambient temperature. While people can use these lamps for illumination, most utilize these lamps for room heating.

Heat lamps are useful for different people. For example, poultry farmers can use them as heating lamps for chicken coops. Owners of hatcheries and vivariums can also benefit from these devices.

The same is true for herpetologists who need a solar power heat lamp for reptiles. These animals are always on the move, requiring heat for optimum muscle development.

People in the food catering business can also need heat lamps to keep their dishes warm. Horticulturists, indoor gardeners, and greenhouse operators can also benefit from the warmth and cost-efficiency of solar heat lamps.

Families who want to eliminate mold and mildew in their bathrooms can also use solar heat lamps. These products are also excellent for preventing condensation on walls, mirrors, and other surfaces.

Households that require a modest increase in their indoor ambient temperature can also use a solar heat lamp. It can complement other space heating methods without increasing electric consumption.

How Does It Work

A solar heat light works like any other solar-powered device. It consists of photovoltaic cells that capture sunlight, which the system converts into electrical energy for storage in a deep cycle battery. A solar bulb draws power from the battery to operate.

Unlike conventional lighting fixtures, solar lights work to increase the room temperature. It does this through the bulb’s inherent design or other lamp elements.

For example, LEDs do not produce as much heat as incandescent bulbs do. That is why many manufacturers increase the LED bulb’s wattage and lux ratings to provide enough heat to any space. Moreover, additional lamp features can concentrate the heat downward for optimum heating.

What Are The Different Types Of Solar Heat Lamps


Solar heat lights come in three types, depending on their infrared wavelengths.

  • Shortwave Lamps – These are the most trusted solar powered heat lights because they are the brightest and hottest fixtures one can use to warm a large room. They are ideal for heating outdoor patios, barns, and other spaces requiring sufficient heating. The top-tier carbon infrared lighting also has a bright light.
  • Mediumwave Lights – These products produce 60% heat, while 40% warms the immediate surroundings. They are suitable for room heating, but not for outdoor uses. An excellent example of a medium wave lamp is halogen bulbs.
  • Longwave Fixtures – These fixtures give off 40% heat and dissipates the remainder in the environment. Longwave lamps can heat and light indoor spaces gradually.

Advantages And Disadvantages Of Solar Heat Lamps

The principal advantage of solar bulbs is cost-efficiency. Families will never worry about their power consumption because the fixture draws its power from sun energy-fed replaceable batteries. As long as the sun shines, the battery will store energy to power the solar lights.

Aside from a solar system’s energy saving capabilities, it is also eco-friendly. A solar powered heater does not rely on electricity, contributing to reduced dependence on fossil fuels.

The disadvantage is that solar powered lights depend on sunlight to recharge. If it is cloudy or raining, the solar panel strip may not gather sufficient power to run the lights. Operating shed lights, outdoor lights, and other fixtures may not last long or produce insufficient heat.

How We Picked And Tested

Choosing heat lamps for chicken coops, hatcheries, vivariums, greenhouses, barns, animal enclosures, and other spaces can be a tedious process. Many factors can play into one’s decision. In this article, we adhered to the following parameters to make a shortlist of products worthy of one’s consideration.

  • Ability to Generate Heat

A solar powered shed light must not only illuminate the storage shed with clear light. It should also act as an external heat source. How much heat a bulb produces is an indirect function of its lux rating. A dim light will give off less heat than a bright light, while a double head lamp will generate more heat than a single light fixture.

That is why we included products with a lux rating of 130 lumens, equivalent to a 15-watt incandescent bulb.

  • Battery Capacity

An outdoor camping light and other solar lights draw power from rechargeable and replaceable batteries. That is why it is essential to pick dry cells with a minimum capacity of 800mAh. In general, the higher the battery capacity, the better the fixture’s space heating and illuminating capabilities. A battery backup is also nice to have.

  • Solar Panel Type

As much as we would like to include monocrystalline panels, these products are expensive. On the other hand, thin-film panels are inefficient. That is why we mainly chose heat lights with polycrystalline photovoltaic cells.

  • Weatherproofing

Most solar heat lights have an ingress protection rating of IP65, safeguarding their sensitive electronics against dust, rain, snow, and other particles. We also picked solar panel heat lamp products with waterproof connectors.

  • Cable Length

Solar heating lights require a cable to connect the lamp to the solar array. One can have a long strip lamp to warm and illuminate a large space. However, one cannot optimize this lighting fixture if the cable between the bulb and the panel is too short. That is why we included products with wires at least three feet long.

  • Other Features

We also evaluated the unique features of each product, including remote controls, lighting modes, and portability. While some people may like motion detected heat lamps, a motion sensor can increase the product’s price. It would be like buying a solar heat lamp Bunnings offers.

Frequently Asked Questions


Are solar-powered heat lamps expensive?

No, solar heat lights are not much more expensive compared to ordinary ones. Whereas solar-powered products cost $15 to $50, conventional solar chicken coop heat lights can also set you back around $14-$48. That’s not even the end of the story – solar lamps will help you save a lot on electricity bills in the long run as well.

Most heat lamps for chicken coops have 0.25 kW. Keeping this bulb lit for 24 hours will lead to 6 kW of electric consumption (24 × 0.25 = 6 kW). Multiplying six kilowatts by 30 days will give us 180 kilowatts. Suppose the electricity in your area costs 0.15$ per kWh. In that case, a single 250-watt heat lamp will cost you $27 monthly.

It should be easy to imagine how much you can save using a chicken coop heater solar unit instead of more conventional systems. One month of solar heater lamp use is enough to offset the initial expense.

How long do solar-powered heat lamps last on a full charge?

The runtime of a solar heat lamp for chickens after a full charge varies across brands, solar panel efficiency, battery capacity, peak sun hours, and LED wattage. Some units might only last six hours, while others can extend their heating capabilities to twelve hours.

A monocrystalline-paneled solar heater lamp for tortoise species and other animals lasts longer than polycrystalline units due to its higher conversion efficiency. Whereas the former can convert up to 23% of light absorbed, the latter cannot surpass the 20% mark.

Batteries can also impact how long solar-powered heat lamps will last after a full charge. As a rule, the higher the battery’s capacity, the more electricity it can hold. Hence, the longer it should last. For example, a solar heat lamp powered by a 2,000mAh battery should outlast a 1,000mAh unit.

However, a high LED wattage rating can drain even a high-capacity battery more quickly than a low-watt solar heat lamp. For instance, a 100-watt LED will consume a battery’s stored energy faster than a 50-watt unit.

How long do solar heat lamps last?

A solar heat lamp outdoor unit is not different from other solar-powered fixtures. It has a photovoltaic panel for collecting sunlight and generating DC electricity. Batteries are also essential for storing solar-derived electrical energy. These components have varying longevity, impacting how long the solar heat lamp will last.

Batteries are the shortest-lived among a solar light’s components, lasting 2-3 years (for lithium units) or up to 5 years (for nickel-metal-hydride). Meanwhile, most LED bulbs have a 50,000-hour lifespan, although it is not uncommon to see a 100,000-hour unit. Hence, you can expect to buy batteries for solar heat lamps more frequently than LED bulbs.

Solar heat lamps with monocrystalline panels have a 25- to 40-year lifespan, while polycrystalline units might last 5-10 years less.

Do solar lights give off heat?

Solar heat lights can give off heat, depending on the light fixture used in the design. In general, incandescent light bulbs produce more heat than compact fluorescent light and LEDs.

A 15-watt incandescent bulb can heat up to 50 degrees Fahrenheit. One will need a 60-watt CFL to produce the same amount of heat.

On the other hand, LED lamps have a heat sink that prevents heat dissipation through the bulb. They can still produce heat, except not as much as incandescent solar lamps.

How can I keep my pigs warm without electricity?

One of the most practical ways to keep pigs warm without consuming electricity is to keep their straw or hay bedding dry.

Covering the pig pen’s entrance at night can also prevent cold drafts from entering, keeping the pigs warm and cozy.

Hog raisers can also install solar lighting in their pig pens. These fixtures can provide enough warmth for the pigs at night or when it is raining or snowing outside.

How many solar panels do I need for a heat lamp?

The number of photovoltaic panels one needs to power a heat lamp depends on several factors, including the solar panel’s power rating and the heat lamp’s power requirements.

For example, suppose one has two 200-watt heat lamps. In that case, it would be advisable to get a solar panel with the same wattage rating.

However, one must understand that PV panels do not work 100% efficiently every time. That is why it would be best to account for inefficiencies by multiplying the solar panel’s power rating by 85%. Hence, if one has a 200-watt solar panel, it may only produce 170 watts.

In the example, the heat lamps require 400 watts. Therefore, it would be more appropriate to get five 100-watt PV panels to produce a total of 425 watts (100 watts x 0.85 = 85 watts; 400 watts ÷ 85 watts is 4.7 or 5).


The best solar heat lamps do more than illuminate a living space. These fixtures can also increase the ambient temperature for healthier growth and development of animals while promoting comfort. Choosing the right product entails understanding various factors, including heating abilities, battery capacity, and weatherproofing.
