Best Solar Panels For Greenhouse: A Comprehensive Buyer’s Guide

A Solar panel not only reduces greenhouse gasses but is also the most versatile power backup tool that has zero carbon emission, can be transported anywhere, and is a complete kit for having clean, stable, and green power anywhere and anytime.

If you are using gasoline or petrol generators or some other fuel power backup sources, the device will eventually end up costing you a lot of utility expenses such as the running cost, and will also burn a lot of carbon that is harmful to nature itself.

Buying Guide Of SOLAR PANELS FOR GREENHOUSE – Infographics

The use of solar panels ends up mitigating this carbon footprint and it also allows you to have expandable and customizable solar ecosystems that can connect with many batteries and offers an unlimited power supply of your desired wattage.

Do you know, that solar panels are the most used power backup sources with Zero Carbon Emissions?

Interestingly, solar panels not only give you a green and environmental-friendly power supply but are also the faster and cheaper energy variants that reduce the running cost and cut short the utility expenses that would otherwise have been wasted on fuel for running the generators and inverters.

Have clean, green, and stable power at much-reduced power and zero carbon emissions? What more do you want from a solar panel?

To be frank, solar panels are not all about being the best and there are certain cheap solar panels that downgrade the whole experience and make the users hate the green power generated by these solar panels.

Apart from the poor quality cheap solar panels. Many good solar panels suck in performance and are all about fancy appearance and high price.

For this reason, solar panels are still overshadowed by the generators and inverters that are still by large in use, be it in outdoor settings or inside residences and corporate buildings.

If done right like most other power backup sources, solar panels can prove themselves to be one of the best media but this will only happen when you make sure to have the best product at hand.

1. How To Determine Which Solar Panel Is Best For Greenhouse?

The market is flooded with many great and overwhelming choices for top-notch and affordable solar panels but all you are looking forward to is to have the cheaper one and guess what, the cheaper one is not always the poorer one.

This is because there are many budget-friendly solar panels that have the best of everything in them. But this doesn’t mean all cheap products can be trusted.

Did you notice that most cheap goods have some compromising points that tarnish their performance or appeal?

An affordable piece may be nice looking to get a start but a cost-effective holistic product is a go-to solution in all situations.

To help you have the best solar panel, we have come up with an extensive buyer’s guide where you can have all the required features under one platform and determine what a good solar panel should look like.

More importantly, what should you look for in a solar panel dedicated to a greenhouse?

So, here we go with our buyer’s guide, and let’s now peek at the things to consider before buying a quality solar panel.

2. Things To Consider Before Buying The Best Solar Panels For GreenHouse:

Given below we have mentioned the most critical things and features that one should pay heed to before finalizing the purchase of a solar panel.

All these features and specs are carefully considered after reviewing and testing the best solar panels for the greenhouse.

Therefore, you may find some different aspects that are not crucial for residential or outdoor solar panels.

For instance, an outdoor solar panel needs to be ultralight and portable as its top priority but when it comes to greenhouses, easy installation and an affordable price certain cheap solar panels downgrade.

So, without any further ado, let’s head straight for the necessary features that should be looked upon in a solar panel for a greenhouse.

Are you ready, let’s get started!

I. Solar Cell Type:

The first and foremost consideration one should make while buying a solar panel, be it for a greenhouse, camping trip, wildlife adventures, or other outdoor ventures, is the type of solar cells of which your unit is made up.

Generally, the two most common solar cell types widely used in the market are:

• Monocrystalline Solar Cells
• Polycrystalline Solar Cells

Monocrystalline solar cells are the most efficient energy converters and this makes them the most desired and the best type of solar cells being used in the construction of solar panels.

Although Monocrystalline solar cells are common and efficient they are also more pricey and this creates room for alternative solar cell types of which Polycrystalline solar cells are the most significant ones.

Polycrystalline solar cells are more budget-friendly solar panels than Monocrystalline ones and are compensated by the lowered prices.

The difference in energy conversion efficiency is not that great to discard the polycrystalline solar panels but if looking forward to the best one in the market, it is better to go with Monocrystalline solar panels.

II. Construction Material:

After deciding on the type of solar cells, you should also determine what construction materials you want your panels to come with.

Typically, aluminum is the best material anyone can ask for the construction of solar panels and is also widely used and abundant in the market.

Monocrystalline solar panels made up of aluminum are the best choice and are also a bit more pricey than the competitors.

In addition to aluminum solar panels, glass is also abundantly used in the making of solar panels and glass solar panels are nothing less than aluminum ones.

There might be a slight difference in terms of the durability of the solar panels differing in aluminum and glass constructions, but there won’t be any difference in the efficiency of the two contrasting construction materials.

Depending on your budget, you can either choose an aluminum solar panel or a glass panel and nothing will go wrong with any of them.

III. Battery Capacity:

Now, breaking out of the construction shell and looking into other specs besides the construction materials, the buyer should peek at the product description and look for the battery capacity and type.

The three most common types of batteries used in the construction of power banks and solar panels are:

• Lithium-ion Batteries
• Lead Acid Batteries
• NMC Batteries

NMC Batteries are a subtype of li-ion batteries and stand for Nickel, Cobalt, and Manganese batteries.

Lithium-ion batteries are the most efficient ones with the most powerful energy-storing option as well as faster charging, better battery life, longer and higher endurance, and better performance.

The life cycles of lithium-ion batteries are way higher than lead acid or other batteries and therefore, having LI-ion batteries is the best choice.

Now coming towards the capacity of these batteries, you should decide, how much power you need and how much wattage is supported by the power bank you are going to use with your solar panels.

The solar panels suitable for greenhouses don’t require batteries as an absolute necessity and therefore, many good solar panels for greenhouses come without the included batteries.

But if you are looking forward to an All-rounder unit that has a powerful output wattage, having a high-capacity battery will be the need.

For example, if you have a portable power station of 2000 running watts such as that of BLUETTI AC200P then you should complement it with a high capacity 2000 watts per hour battery.

But if you have a 300 watts power station, an 88 watts per hour battery may prove to be more than enough for you.

Therefore. Determine how much power you require and if you are going to connect any power station with your solar panels or use them as standalone devices.

If using them as standalone devices, there will not be any need to mind the battery capacity but if you have to power them along with portable power stations, having a suitable battery capacity is necessary for a cost-effective solar panel.

IV. Energy Conversion Efficiency:

One of the crucial and most talked about considerations of solar panels for the greenhouse is the energy conversion efficiency and you would have noted that this feature is mentioned thoroughly in all the products we have reviewed earlier in detail.

The energy conversion efficiency of good standard Monocrystalline solar panels ranges somewhere between 21.8 to 24% ratings and polycrystalline and other construction materials have way lesser efficiency than this rating.

This could be understood by considering a typical example where a solar panel receives 100 sun rays and with an efficiency of 22% only 22 of these captured solar rays will be converted into electric power and the rest will be wasted.

Therefore having a higher energy conversion efficiency is the best thing and this will be helpful in faster charging and low waste rate.

FAQs (Frequently Asked Questions)

1. What Type Of Energy Does A Greenhouse Use?

The primary energy type used in a greenhouse is Heat energy but this heat is generated by the use of various other energy types that include lighting, pumping, and ventilation.

2. How Much Energy Does A Greenhouse Consume?

According to energy audits in a typical greenhouse, the annual energy consumption of a greenhouse is somewhat between 1 to 2 KWh per square foot floor area.

3. What Is The Greenhouse Effect?
