What is a Solar Panel Kit for Home?

Solar panel kit is pre-packed solar equipment that after installation can form an operating solar power system for your home. Almost all solar kits come with everything you need to have a working solar system (complete equipment). For some kits you may need to buy additional items, so you should be careful. 

Solar panel kits can vary in price depending on their build, power generation, size, and components. Therefore, they can cost from a few hundred up to thousands of dollars. Once you choose and buy a solar panel kit, it will be shipped to your home and all you have to do is install it yourself (DIY- do-it-yourself).

Before buying a solar panel kit, you should do some research and calculations regarding current energy consumption in your home, and how it will change in the future. Thus you will know how much solar power and how many panels you will need. You should also decide whether your solar power system will be grid-connected, off-grid or hybrid.

Here are the basic components that you can expect in most solar panel kits: solar panels, solar inverter, batteries (off-grid), charge controller (off-grid), mounting hardware, wiring and connectivity parts. You can choose between two types of solar panels: polycrystalline and monocrystalline. Monocrystalline panels are more expensive, more efficient, and more heat resistant.

Solar panel kits are suitable for small homes. There are solar panel kits for large homes but as you go up in size (1,000W and more), solar installations become more complicated. It doesn’t make sense to install a large solar panel system yourself. And If you are not sure about your knowledge it is recommended to seek professional help. Installing your solar panel kit may save you money but keep in mind that it can be time-consuming, challenging, and even risky in terms of safety and how to do it right. Also, if your solar panel kit is grid-tied you have to check whether your utility company allows self-installed solar systems to connect to the grid. 

If you are absolutely beginner to solar electricity it is a good idea to buy a solar starter kit. Starter solar panels kit won’t be able to fully power your home but it is just a few hundred dollars and includes the parts you need to start seeing if solar is right for you. It can power some of your electric appliances and it is usually grid-connected, which means that it will work with the existing grid. Typically solar starter panels ranging from 50W - 400W.

Solar panel kits are a good option for garages, farms, boats, caravans and off-grid cabins.

SunTree Solar Charger

A mini solar tree charger can be a useful and unique eco gift. We may see it as a mini model of the solar-powered tree charging station about which I wrote in my previous post. 

A mini solar tree charger consists of several small solar panels that resemble leaves on a tree, rechargeable battery, and USB ports. Solar tree charger is an eco-friendly way to charge your mobile phone and tablet in your office or home, using solar energy. It absorbs the sun’s rays and uses solar energy to charge your mobile devices. Even when your phone is not plugged in it will continue to charge the built-in battery ready to transfer the power to your device. 

Here are three models of mini solar tree chargers. You can find on the market only the first and the second one. The third model is looking for investors. 

SunTree - this solar tree charger gives you an awesome way to charge your devices. It is made to look like an actual tree - has a wooden bamboo trunk and branches, and each branch has a small solar panel on the top of it. SunTree has 9 solar panels to charge your mobile devices using PV technology. You can place the SunTree next to a window and it'll charge its internal battery, and in turn, that battery will charge your phone, tablet, and other electronic devices. SunTree is designed by XDDesign, Netherlands. 

Ginkgo Solar Tree - It is made of aluminum, recycled plastic, and bamboo. Ginkgo Solar Tree is a mini solar charging station inspired by the Japanese Ginkgo tree. Gingko solar charger is an environment-friendly source of power. It gets its power from the sun, so it’s green and very easy to use, you just need sunlight. Ginkgo Solar Tree charger aims to make solar energy more approachable and user friendly. Bringing solar energy down to smaller gadgets can help reduce harmful emissions to the atmosphere caused by the growing need to power mobile phones and tablets. Ginkgo Solar Tree can charge your iPhone or iPad up to two times after charging. It has a powerful 4000mAh battery and two USB ports. This product is also designed by XDDesign, Netherlands.

Electree Mini - inspired by bonsai trees, this little solar charger tree collects sunlight to charge your gadgets attractively. Electree Mini is a product of the designer Vivien Muller, who worked together with an electrical engineer to turn his idea for the tree into a reality. This small solar charger has 27 flexible silicon solar panels that can be easily adjusted to harness the maximum amount of sunlight. The device can be used to directly power your gadgets when sunlight is available or use the internal batteries that store solar energy during daylight time. The Electree Mini turns into a miniature light show when the darkness falls. You can also change the color of the LED lantern just by rotating the Electree Mini. The mini solar charger isn’t yet strong enough to charge a tablet, but it can charge your phone or smartwatch once per day.

Solar-Powered Tree as a Solar Charging Station

A solar-powered tree is a type of solar-powered charging station that can capture solar energy and provide free electricity from the sun to public places.

In 2010, a group of students In Belgrade, Serbia developed the first solar-powered tree in the world - the Strawberry Tree. This is the first public solar charger for mobile devices. The innovative solar charging station has Wi-Fi, USB ports and 16 chargers for various types of mobile phones and other portable electronic devices. The Strawberry Tree won first place in the European Commission’s "Sustainable energy week 2011" competition in Brussels, in the category “Consuming”. 

Another example of a high-tech futuristic solar-powered tree is eTree created by the Israel-based company Sologic. This “tree” is a place to take a break while recharging your mobile gadgets and accessing the Internet via free Wi-Fi. Similar to a real tree, the eTree has brown trunk and branches. But, instead of having leaves, there are solar panels that are angled towards the sky. The eTree has USB ports and provides a small amount of lighting during the night. There are also benches located beside the solar-powered tree. The first eTree was installed at a nature reserve in Israel. 

Solar-powered palm is a variation of a solar-powered tree. This stunning solar design absorbs sunlight during the day through "leaves" covered with ultra-thin solar modules and converts to an exotic solar-powered lamp at night. The trees’ energy can also be used to charge mobile devices through its integrated USB connection. 

The first Smart Palm installed on Jumeirah beach in Dubai is one more example of solar-powered palm. Now, these Smart Palms, or "self-sustaining community tech hubs" are on every public beach in the city, as part of an ambitious plan to convert Dubai into a "Smart City". There are 50 solar-powered Smart Palms on public areas, and each of them provides Wi-Fi, USB socks for mobile phones and tablets, as well as updated information on the weather and local attractions. The solar-powered palm trees are illuminated at night using the system’s battery where solar energy is stored. 

And finally, I should mention solar-powered supertrees, although they are not solar charging stations.

There are amazing gardens in Singapore - Singapore’s Gardens by the Bay with 18 manmade steel supertrees varying from 15 to 50 meters in height. 11 of them have solar photovoltaic systems to convert sunlight into electricity, so they can light up at night. The supertrees also function as vertical gardens, air venting towers, and rainwater collection devices. These incredible constructions are designed by Grant Associates. 

The above solar-powered trees are just several examples of the beautiful innovative design, which is also a growing solar trend in the world.

Solar-Powered Charging Stations for Mobile Phones, Cameras, and Electric Vehicles

Solar-powered charging stations are innovative solar-powered designs that can be used in public places when no electricity supply is available. You can see them alongside the streets, in the squares, and even as “umbrellas” attached to benches in public parks. On the market, there are also smart solar benches and they are an excellent addition to existing urban furniture.

Solar-powered charging stations are great to allow people to charge their small devices such as mobile phones, laptops, or cameras outdoors. Some of the solar-powered charging stations can power electric bikes, scooters, and cars, so recharging your car’s batteries is often cheaper at one of these stations. Solar-powered charging stations can provide also lighting, WI-Fi, give insight about the environment, and display information on a digital screen.

All solar-powered stations work similarly, although they might differ in terms of size, capacity, and the type of charging that is available. Each solar-powered station consists of an inflexible or flexible solar panel (or panels), battery system, charge controller, and inverter.

The benefits of solar-powered charging stations are numerous. First of all, they produce electricity without any emissions, making them one of the most environmentally-friendly technologies. Unlike coal, nuclear or gas-powered plants, solar energy does not produce emissions, nor toxic byproducts. And it is a renewable source of energy.

The implementation of solar technology in public places gives us free or cheap energy. Especially, for those living far from the electrical grid, solar charging stations for mobile phones can be the only way to stay connected. It is no surprise that in the developing countries more and more solar-powered charging stations are appearing. In countries where electricity is not accessible to all, public solar-powered charging stations for mobile phones are very popular. (Read this article)

Last but not least, with the solar-powered charging stations, we become energy independent and can spend more time outdoors. When we know that we can charge our mobile phones and other electric devices outside, in the streets and in the parks, it gives us more freedom and flexibility to spend time outdoors and in nature.

Solar-Powered Backpack

A solar-powered backpack is one of the recent environment-friendly solar innovations which become more and more popular. It allows the hiker or traveler the opportunity to keep their electronic devices charged anywhere they go using solar energy. 

We live at the age when we are constantly connected to one device or another such as smartphones, MP3 players, tablets, laptops, so the importance of having a source of power with us has never been greater. Here comes a solar-powered backpack. It can harness enough solar energy to keep us connected with the world and it is ideal for people who like to take hiking trips or go camping.

The solar-powered backpack has a small solar panel attached to its outer surface so we can capture the sun’s rays. The interior space includes a storage battery and other components. The solar panel is lightweight, waterproof and can produce up to 10 watts of power. 

Other components of the solar-powered backpack include a flexible mono-crystalline or thin-film solar panels, charge controller, a variety of cell phone adapters and a USB plug for your MP3 player.

With the solar-powered backpack, you can also power a GPS, a travel lamp, a digital camera, a palm pilot, and other rechargeable electronic devices.

The solar-powered backpack has a lithium-ion battery pack inside to store this energy. NASA and the US Army have used copper indium gallium diselenide (CIGS) solar cells for its unbreakable strength and flexibility.

A solar-powered backpack known as REPPS (Rucksack Enhanced Portable Power System), was first used by the US army for communication equipment in 2010 in Afghanistan. The US Air Force had previously used solar panels on shipping containers, developed by Lockheed Martin. And the Marines developed suitcase units of foldable solar panels which can also be carried as a backpack.

A solar-powered backpack can also be used for international aid, disaster relief, and humanitarian relief efforts where power from the utility grid is not available. (read this article)

Several companies are manufacturing solar backpacks and they range in price from $75 to $500.
