Hi,
New to the forum and looking for some quote advice if possible.
Had 4 quotes for bungalow in North West with SE/SW roof at 30 degree tilt as follows:
1) 4KW: £7K inc vat
- 16 x Suntech 250-20Wd Poly Panels
- Power One PVI3,6-OUTD 3.6Kw Inverter
- K2 Roof Mounting System
- Yield Reduction due to shading (1%) - PVSOL
- Estimated annual output: 3690kWh(PVSOL)
2) 4KW: £6.2K inc vat
- 16 x JA Solar JAM60-250w Mono Panels
- Power One Aurora 3.6Kw Inverter
- Roof Mounting Kit
- Yield Reduction due to shading (<20%) - SAP2009
- Estimated annual output: 3286kWh(SAP2009)
3) 4WK: £5.6K inc vat
- 16 x Renesola 250W Virtus II Poly Panels
- Samil Solar river 3680TL Inverter
- Roof Mounting Kit
- Remote Monitor
- Yield Reduction due to shading (<20%) -SAP2009
- Estimated annual output: 3286kWh(SAP2009)
4) 3KW: 5.2 inc vat
- 12 x Suntellite 250W Mono Panels
- Samil Solar river 3300TL Inverter
- Schletter roof mounting system
- GEO Solo Remote Monitor
- Yield Reduction due to shading (8%)-PVSOL (<20%)-SAP2009
- Estimated annual output: 2430kWh(PVSOL) / 2464(SAP2009)
Quote 4 was interesting as surveyor/installer calculated that a 16 panel install would get 12% shading after taking account of tree and a neighbouring property.
Hence he recomended 12 panel 3KW system.
Any advice in which looks like the best system in terms of quality, performance and longevity?
Thanks in advance for any replies.
