There is no greater sustainable energy source than the sun. Mankind has been trying to take the most from it since PV panels were invented. There are all sorts of DIY projects involving solar panel and harvesting solar energy. However, most of the PV panels have a low efficiency and even more, their performance is affected by the sun movement and setup location.
Before we go forward, I must mention that this is not an add for the Rawlemon company and I’m not linked with them in any manner.
Personally, I’m trying to stay up to date with the news regarding cheap, sustainable energy and during my browsing sessions I’ve discovered there are some people aiming to squeeze the most juice out of the sun. At least this is what they are saying.
These guys developed a new solar power generator that involves the use of Multijunction cells, which are used also in space applications, and a ball lens to capture the sun rays. In addition to that their system also tracks the sun movement and it’s able to concentrate even diffuse light.
“By using a high efficiency Multijunction cell, we have reduced the cell surface down to 1% compared to the same power output as a conventional silicon cell in optimal conditions. In combination with dual axis tracking, our system generates twice the yield of a conventional panel. In addition, our smaller cell area has a lower carbon footprint because its production requires fewer precious semiconductor or other building materials. “
They developed a variety of products, including some chargers for mobile phones and tablets.
I’m looking at these products as they might be ideal when it comes to having an off-grid energy source. At a first glance I’ve drawn some quick good and bad assumptions for their biggest generator which features a water-filled acrylic-polymer lens, as opposed to the solid lenses of their smaller models.
Here are the details provided by the manufacture on their webpage:
“It comes with a hybrid collector to convert daily electricity and thermal energy at the same time. While reducing the silicon cell area to 25% with the equivalent power output by using our ultra transmission Ball Lens point focusing concentrator, it operates at efficiency levels of nearly 57% in hybrid mode. At nighttime the Ball Lens can transform into a high-power lamp to illuminate your location, simply by using a few LED’s. The station is designed for off grid conditions as well as to supplement buildings’ consumption of electricity and thermal circuits like hot water.
It is easy to transport and install. The support frame includes all the plugs you need to connect to the local grid. It also holds a security protection panel behind the collector. “
And here are my conclusions for this solar power generator:
- This solar power generator looks cool, first of all. But when it comes to survival, the looks come last.
- The tracking system of this solar power generator is able to track the movement of the sun and the moon to get most of the light
- It is wind resistant and it’s not affected by weather conditions compared to PV panels. However, I doubt that it will stay unscratched during a hailstorm
- It’s a solar power generator that provides 3.4 kW per day, which should be enough for an off grid survival location
- It’s less costly compared to PV panels that are capable of the same output.
- This solar power generator is heavy, it weighs a whopping 7385 pounds! I don’t think it’s possible to install it by yourself.
- It’s not mobile and you can’t run out with it due to its size and weight. If you have to change location you will have to leave it behind.
- You cannot easily hide this solar power generator since it needs to stay in open places . Its size is not negligible (its 12 feet high).
- It looks fragile, as I mentioned before, it would be good to know how this solar power generator behaves during a hailstorm.
- It’s still costly for an off-grid solution.
The bottom line is: the design is a thing of beauty, but we can’t know for sure how much more effective this solar power generator is, compared to solar panels. Unless tests and testimonials from people who bought it will surface on the web, we won’t spend money on it. Even more the size and weight, it’s a big minus from the prepper’s point of view. Not to mention the current price of this solar power generator is quite high.
However, I’m thrilled to see new innovations in this field and I’m looking forward for future updates.
If you have info on the product based on your direct experience with this product, feel free to share them with us in the comment section. I would love to hear more about it.
Stay Safe out there!
