Knight Optical can offer you Stock and Custom Fresnel Lenses, for concentrated photovoltaic applications in a range of materials such as PMMA Acrylic and Borosilicate. CPV is an application which generates electricity from sunlight. The key difference between this technology and conventional photovoltaics (solar panels) is the inclusion of optical components. Utilising optical components which focuses the sunlight onto solar cells increases the efficiency of the electricity generation. Knight Optical provides fresnel lenses which consist of a flat surface with interspace concentric steps whereby each step corresponds to the surface of a conventional lenses. PMMA Acrylic is a preferred material for CPV systems as it is very lightweight when used in a large size. Specialist grades of PMMA are also utilised which absorb the UV light and thus reduces the effects of solarisation i.e. the yellowing of the optical material due to exposure to UV.

DEKS FastFlash Solar Flashing, a flexible flashing for the bottom edge of in roof solar installations. Its a fully adhesive butyl backed flexible flashing used for sealing the bottom edge of in roof solar installations, creating a wind and water tight solution which is easier to apply than many of the OEM solutions. The product stretch enables it to seamless follow the contours of the roof. Available in black, light grey & dark grey in various widths.

Allows up to 10 cables to be taken effectively through any tile or slate roof - Avoids risk of damage or pressure on cables by isolating from tiles or slates and provides a complete weatherproof seal. Black EPDM cone, features Nu-Lead® acrylic coated lead base or aluminium base.

The Advance Solar EnergyManager is a tried and tested thermal store design with an internal heat exchanger and shunt pump arrangement resulting in delivery of hot water equivalent to the volume of the tank at 43ºC. The solar version has a dedicated solar coil which reduces energy bills and reliance on fossil fuel. The solar thermal panels will contribute to heating and hot water during periods of solar gain. The shunt pump is pre fitted and wired to activate when taps or showers are turned on. The EnergyManager comes as shown above with wiring centre for installers to complete the wiring for the rest of the system. Full instructions for wiring the total system are included. At 65ºC operation the EnergyManager is perfect for underfloor or low temperature radiator circuits and offers efficiencies due to the temperature being lower than most thermal stores. As a thermal store it can reduce boiler cycling and act as a buffer for heating.

The CTT-EC-HV406L energy storage system has a wide range of applications, including but not limited to renewable energy integration, grid assistance services, commercial and industrial applications, and emergency response scenarios. In solar or wind farms, it can balance energy production with demand and improve the utilization of renewable energy. In the power grid, it provides auxiliary services such as frequency modulation and peak regulation, which helps to enhance the stability and reliability of the power grid. In business centers or industrial parks, it can be used as a backup power source or for peak cutting and valley filling to help reduce energy costs. In emergency situations, such as natural disasters, it also provides critical power support to ensure the normal operation of rescue and communication equipment.
