The Recycler Toy

This is the best toy that we have started to sell in my opinion as the end results can take you anywhere.



This toy combines the themes eco energy and recycling together.

Collect bottles, cans and CD's and recycle them to toys and have fun playing with it !



The Solar Recycler set has parts to make 6 different models combined with recycled materials.



Teaches children how to re-use materials and the power of solar energy at the same time.



Fun and educational.

 
The Recycler

For children but for parents as well !



Great for school’s craft lesson, Scout and Brownie packs, Competition to make the best recycled product .  As this can make anything you would like out of  old bottles cans etc… the toys that you can make are endless and just needs a child’s never ending  imagination.

Security lights



Are you looking to add security to your home? With solar motion sensor lights, you will not have to hire an electrician or run expensive wiring because the sun powers them. You can place a solar motion sensor light anywhere around your property. Solar security lights are perfect for entryways, walkways, sheds, patios, decks, steps or anywhere you need some light at night. If security is your priority, position the solar motion sensor light to cover dark areas of you yard, around bushes or trees, fence gates, patio doors or anywhere to deter intruders.
Overall, solar security lights are very cost effective and a great addition to any home security system

Siting your off grid panels



Siting for your off-grid panels
  • Latitude & Solar Irradiation - The closer to the equator, the more sun we get. Ironically, the hotter the solar panel, the less efficient it performs and so peak outputs are often seen on a cold, clear sunny day. When designing an off-grid system, the irradiation for the least sunny month of the year is used, as this will be the worst case scenario.

  • Shadows / Shading - A complete 'no-no' with solar pv. Beware of long mid-winter shadows from tall trees or buildings. Shading has a massive detrimental effect on the output from a solar pv module and needs to be avoided wherever possible.

  • Angle of Tilt - Off-grid solar pv tilt angles are normally optimised for the worst sunlight months of the year. Generally speaking, the lower the sun is on the horizon in mid-winter, the steeper the optimum angle of tilt of the solar panels.
A rough rule of thumb for sites in the northern hemisphere (to optimise tilt angle for the winter) is to add approx 15 degrees to the latitude. For example, London is 51º and in the winter add 15º. Thus, optimum winter tilt angle = 66º tilt from the horizontal.
Ideal orientation in the northern hemisphere is due south, and due north in the southern hemisphere.

  • PV Mounting Structure - The type of solar pv mounting structure will depend on the site and the optimum angle of tilt. Common solutions include ; tilted roof mounting, flat roof mounting, ground-mounting and post mounting.
Many larger off-grid solar pv systems are ground-mounted and smaller pv arrays are post-mounted, as these both allow ideal orientation and provide a steeper angle of tilt than most roofs.
Tracking mounts are also available, although it's often far cheaper & more reliable simply to increase the size of the pv array rather than introduce moving parts to the system.

  • Cable Run Distances - The pv array ideally wants to be sited within about 50m of the battery bank, although this all depends on the site and the pv array voltage. Systems can be designed to allow up to 200 to 300m of cable run, although long cable runs can be expensive.

  • Snow - If snow is to be expected regularly, a steeper tilt angle may be selected for the pv modules. Due to the dark surface of the solar module and the fact it's facing south on a tilt, when the sun shines the snow thaws and slides off fairly quickly.
  • Dust - In hot and sandy locations, dust may be a challenge and may need to be manually cleaned in the case of a sand-storm or dust-storm. Again, steeper tilt angles can help to reduce dust build-up.
  • Cleaning - In rainy locations, most solar pv modules will do a reasonable job of self-cleaning. However for some locations it will be necessary to arrange occasional cleaning of the pv glass. At the very least, we would recommend manual cleaning once per year, and ideal timing would be at the end of the summer, early winter.

  • Planning Permission - Generally speaking, in the UK, if the building is not in an SSSI or conservation area, and the solar pv panels are mounted flush to the roof, planning is not required. If you need any further information, contact your local council's planning department.
