Case Study 1 - Challenge

Client had built office extension to house and wanted to reduce electricity consumption by using renewables to offset energy used.

Solution.

The room is used as an office and power was required for lighting, pc, TV and associated equipment.   With minimal usage during the day but several hours required in the evening.   A system of Deep Cycle batteries and inverter/charger were installed along with solar panels mounted on the flat roof to charge the batteries.   Mains power is used to supplement the charging when the sun does not offer any charge.

With ever increasing energy costs, unreliable grid connection that is majority foreign owned, we offer energy cost reduction advice linked to a broad spectrum of solutions including renewable's, - wind, solar and water energy.   The requirement to reduce carbon dioxide emissions and reliance on expensive and unsustainable of fossil fuels means that we have to take more control of our energy needs.   By being able to supply some or all of our electricity through renewable's we are able to reduce our carbon footprint and go some way to reducing existing energy.
Case Study 2 - Challenge

A North West company had designed a mobile CCTV camera system that was to be mounted on a hydraulic tower on a trailer, the specification required it to be portable and had to have sustainable power for 24 hours per day for several days without mains connection.

Solution.

12 Voltz designed a system based on large deep cycle batteries, with a design life of 10-15 years which are kept charged by both solar panels and a micro wind turbine.   The turbine is an established dc 200 watt turbine and the solar panels are 24 volt 165 watt solar panels reduced to 12v through an Outback charge controller.   The system can sustain the battery power for several weeks without charge.

 

Case Study 3 - Challenge

Large 9 bedroomed house in midlands, fully occupied and spending over £500 per month on electricity.   Wanted cost effective way to reduce energy costs.

Solution.

Full survey carried out, house is in conservation area, so installation of renewables was not possible.   However, full report showing changes to existing appliances and accessories and a slight change of lifestyle reduced monthly bill to around £280
Case Study 4 - Challenge

Remote house using generator as prime power source.   Household was expanding and required more cost effective way of producing energy.

Solution.

Grid connection was not an options as cost was inhibitive.    Solution was to install large 48v battery bank with dual inverter/charger system and 3Kw wind turbine with generator as back up charging every 2nd or 3rd day in calm conditions
Case Study 5 - Challenge

Stable lighting in remote fields has always been an issue, how do we get lights to work with no power, Generators are expensive and noisy to run.

Solution

Our early solution was to use solar panels to charge a battery and use our own in house 12v Bulkhead lights to light up the stables, nowadays, we use wind power, this is more effective in the winter when more power is required.   From this we can give sufficient power for mains compact fluorescent lights to be used, and sufficient power to light up menages etc.

Case Study 6 - Challenge

To provide power for a smallholding in a tree lined quarry.

Solution

Fortunately a stream flowed through the land next to the smallholding.   Mounting the Ampair UW in the stream gives around 3Kwh per day which is sufficient to keep a battery topped up to give basic power for a bit of lighting, tv and a fridge.   A generator is used as back up and for regular bulk absorbtion charging and equalisation charging of the batteries.
