PV Benefits Simplicity and modularity Reliability and security Independency Environmental Benefit Maintenance Free Economic cost - effectiveness Sustainability Innovation Aesthetics Zel, Bochum Germany (230KWp)

Simplicity and modularity PV solution is simple to operate, requires almost no maintenance Modular solution, can easily add or remove solar panels or combine different groups of arrays PV module on balcony Modular Grid Connected System

Reliability and Security PV panels are a proven technology. More than 35 years in commercial applications Tested and installed under extreme environments PV panels under extreme environments, taken from Kyocera quality Modules Catalogue

Reliability and Security Guaranteed up to 80% performance over 20 years PV provides an extra energy source making the system more reliable PV Off-Grid System in the South Pole

Independency Producing your own energy. No dependency on the volatile oil! PV Panels used for Camping

Environmental Benefit No emission of greenhouse gases No environmental pollution No noise pollution

Maintenance Free No maintenance required No change of equipment for long periods of time

Economic Cost Effectiveness ROI ~ 5-7 years Price of oil expected to rise significantly => Photovoltaic solutions become more and more cost effective More governmental support for renewable energies (subsidies) Introduction of net-metering and feed in tariff Man killing himself with fossil fuel (environmentally and economically)

Sustainability Established 1984! Lifetime of PV solution: PV panels 35 years lifetime Solar electronics also have a very long lifetime 43kW Grid-tie System 1,016 Modules Taken from Why Kyocera presentation Taken from Steca off-grid catalogue

Innovation Why not be the leader in the green revolution?!
