BESS RETROFIT
BESS Retrofit — Add Battery Storage to Your Existing Solar PV
Already have commercial solar panels? Novalux Solar retrofits battery energy storage systems to existing solar PV installations, dramatically improving your returns and energy independence.
Commercial battery systems typically qualify for 100% capital allowances — a year-one tax deduction. Ask us for the figures for your business.
