Solar Power Supplies Off Grid

PV array is only charging source 6 to 10 days battery autonomy Best for loads under 150W Best with DC loads, but AC loads okay Pole, ground, wall, and trailer mounts Uncontrolled battery environment Can include battery charger for use with portable generator Solar Power Supplies - SPS

Optional Features: Inverter for powering AC loads AC battery charger, which can be connected to a portable generator Maximum power tracking to get most out of PV array Low voltage disconnect to protect batteries Low voltage and high voltage alarms Remote control & monitoring

SPS Case Study Customer: Greenstar Engineering Application: Remote SCADA Location: New York State Load: Waste site monitoring, 25W, 12V Solution: SPS12-246/324G (12VDC, 246W PV, 324Ah battery) (2) Sharp 123W, 12 VDC PV modules (1) Morningstar charge/load controller (3) East Penn 108Ah solar gel batteries (1) PRC1000 programmable relay controller Programmable relay allows scheduled load control Approximate Cost: $2,300 Customer Feedback: Working Great!

Hybrid Power Supplies

Hybrid Power Supplies - HPS Designed for applications with larger electric loads or requiring greater reliability in areas with highly variable solar resources. Incorporate an auxiliary engine generator sized to provide 25% to 75% of the load energy, with the balance supplied by the solar array. The generator operates at full load providing optimum energy delivery, and higher system fuel and maintenance efficiency.

Hybrid Power Supplies - HPS PV array and generator charge batteries 4 to 7 days battery autonomy Best for loads larger than 200W Best with DC loads, but AC loads okay Skid and trailer mounted systems pre-integrated Semi-controlled battery environment For larger loads, heavy-duty or two alternating generators recommended Wind turbines can be added as charging source

HPS Case Study Alamosa PCS (Sprint) Alpha HPS /1500/6 4 to 7 days battery autonomy 900W PV Array 1500 Ah MTI battery bank 6 kW AlphaGen DC generator Skid Mounted Installed in one day! Annual recurring cost savings (fuel and maintenance) ~$20,000 / yr Including Capital Cost: Pay Back in 1-2 years

Grid-Tied Solution Planning

Solar Panels / Photovoltaic Panels Alpha Panels have mono crystallin cells inside Others use poly crystallin cells (less efficiency but cheaper) Thin layer (a-Si, amorphus Silicon, CIS, CdTe) Concentrators III-V (future, tracker needed)

Solar Tubes

Solar Foil

Technical Details Amorphous Silicon Solar Cells UV stable teflon foil Glued to metal sheet or foil Special developed glue for long lasting connections CE and SKII approved 92W per unit High voltage – one unit can feed one PV inverter

Applications Roofs that cannot support the weight of crystalline modules Roofs not oriented to the south – complete roof can be covered Large roofs where efficiency is not the point Curved surfaces

Inverter: e.g. SMA 3800

Inverter: Connecting to Grid

Communication: TCP/IP, RS-485
