It is not only the transition itself to solar energy but our awareness, insight that we can reuse space on the roof and windows to place solar panel capacity. The biggest challenge is our daily habits and mindset to buy only the renewable designed products online which are not... produced with oil/wood generated energy. Choose long life led light for example and renewable solar panels / battery solutions based on LiFePO4 (LFP) elements.
Large savings example (private and company costs):
TIP1 Replace your car by a hybrid with min. 55 km charge range; The extended range on normal E10 fuel is 750km for a medium size hybrid car of 2021 of later. So any normal requirements you had for your car on fuel are integrated in hybrid car/trucks. (25% Off the grid with extended range on the grid using AC 230V). Why a plugin-Hybrid and not an EV(Electric Vehicle) in 2021, the range of an EV max 200km is too short: You will get stuck during your working hours on the road without fastcharge spots in the country, safety FIRST!), charging at home not possible without a big investment. Shell/BP/Mobile/Engen, where are the hybrid AC plugin+hydrogen service stations around the world with 2 hour parking locations for solar energy load/storage 230V AC?
Why? You can save 55x7x52, more than 20.000km fuel: You saved a brand new car of 30.000 EUR in 15 year reducing CO2 with a fuel price of 2,07EUR p/liter.
TIP2 Take 10 solar panels (both shadow/sun side) on your house to convert to AC power directly and storage: Your can earn back your 10 solar panel investment within 5 years and still by your new car in 15 years.
TIP3 Charge at home using a plugin-hybrid: This car can drive anywhere in the world. You need to buy a type 2 cable and long tool cable of 10m to plugin in a normal 1 phase plug at home (16A). for charging 3-4 hours max.
A Major change in the mindset of EU states
Starting in 2023 all solar battery systems (including Sustainable LFP battery solutions) need to be proven renewable by law before company's outside the EU are allowed to import new solar battery systems or car battery systems.
- Q2 2023: More stringent targets for collection will be included in the new rules for portable batteries (45% by 2023, 63% by 2027 and 73% by 2030) and for light means of transport batteries (51% by 2028, 61% by 2031).
In addition, all waste from light means of transport, automotive, industrial and electric vehicle batteries should be collected free of charge for end-users, regardless of their nature, chemical composition, condition, brand or origin.
Solar for windows does not block the view
A team of researchers at Michigan State University has developed a new type of solar concentrator that when placed over a window creates solar energy while allowing people to actually see through the window.
It is called a transparent luminescent solar concentrator and can be used on buildings, cell phones and any other device that has a clear surface.
Besides the solar energy coming through the normal window to the panel inside placed directly behind the window or on walls having not the perfect angle or partly in the shadow can be still interesting when the capacity in Watt per Hour is <NeededCapacityInWatt>+25% or more. Investment on return is a little lower but the CO2 reduction and generated energy makes it for the goals enough sustainable to redesign our classrooms, apartments, houses and buildings.
Also spreading the solar hours over the day might be a good calculated reason to add solar panels at 2 sides of a building or roof instead.
Also using one window to reduce the light inside the house but use the window for solar energy instead is a good choice to make yourself.
Always use a MPPT controller to convert DC electricity coming from a solar panel to the backup battery or power station of 12 v to save the battery life of a LiFePO4 sustainable battery.

Portable offthegrid-energy or onthegrid?
We prefer to offer you offthegrid-energy without or with ups to make you independent from grid providers.
- Some grid providers offer you to reduce energy costs by delivering back solar energy on the grid but give you a higher risk by depending from the local economy or grid provider creating a too high AC voltage after restoring from loadshedding or a power down: Be aware this can damage your devices permanently.
- Use your energy directly offthegrid during the day for your EV car or save the extra energy during the day in a LiFePO4 storage solution close to the solar panel as a backup for a power outage, power shortage, extended EV range or a cloudy day.
- Behind a window: Protect the portable LiFePO4 battery for high temperatures >30 degrees from the sun by placing it behind the non-transparant solar panel for example and only charge the battery with a solar panel using a in between MPPT controller.
Estimated capacity
To overcome a cloudy day a home backup solution or class room solution has enough power using a backup storage capacity of 5kW / 7,5kW. If necessary you can duplicate the solution for more capacity working independent per class room or apartment level. As long as de backup solution can handle a max. 200W solar panel for a window / wall / roof to charge at the same time during usage. Always estimate +25% calculated capacity is our advice based on the total capacity in Watt p Hour of your devices in the office / room / class room / department level. No claims can be made on the expected capacity calculations we give you on this website. They should help you to make the first steps.
