That was standard at the time\u2014but it\u2019s now considered low by today\u2019s standards.<\/p>\n<p>These older systems typically:<\/p>\n<ul>\n<li aria-level=\"1\">Occupy more roof space for the same output\n<\/li>\n<li aria-level=\"1\">Generate less power per square metre\n<\/li>\n<li aria-level=\"1\">Have reduced output due to age-related degradation (up to 10\u201320%)<\/li>\n<\/ul>\n<h2>What Can Modern Panels Produce in 2025?<\/h2>\n<p>Today\u2019s premium solar panels produce 400W to 500W or more per panel, and they\u2019re more efficient in low-light conditions. That means:<\/p>\n<ul>\n<li aria-level=\"1\">Up to 2x more energy output from the same footprint\n<\/li>\n<li aria-level=\"1\">Fewer panels needed for the same system size\n<\/li>\n<li aria-level=\"1\">Higher returns over time, especially when paired with battery storage<\/li>\n<\/ul>\n<h2>Example Comparison: Old vs New System<\/h2>\n<p>Let\u2019s compare a typical 10-year-old setup vs a modern upgrade:<\/p>\n<table>\n<tbody>\n<tr>\n<td>\n<p>System Type<\/p>\n<\/td>\n<td>\n<p>Panel Wattage<\/p>\n<\/td>\n<td>\n<p>Number of Panels<\/p>\n<\/td>\n<td>\n<p>Total Output<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td>\n<p>Original System (2012)<\/p>\n<\/td>\n<td>\n<p>250W<\/p>\n<\/td>\n<td>\n<p>16 panels<\/p>\n<\/td>\n<td>\n<p>4.0kW<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td>\n<p>New System (2025)<\/p>\n<\/td>\n<td>\n<p>500W<\/p>\n<\/td>\n<td>\n<p>16 panels<\/p>\n<\/td>\n<td>\n<p>8.0kW<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td>\n<p>New System (2025)<\/p>\n<\/td>\n<td>\n<p>500W<\/p>\n<\/td>\n<td>\n<p>8 panels<\/p>\n<\/td>\n<td>\n<p>4.0kW<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>So, with the same number of panels, you could double your system\u2019s output.<\/p>\n<p>Or, if your energy usage hasn\u2019t increased, you could use half as many panels to generate the same amount of power\u2014ideal for homes with limited roof space.<\/p>\n<h2>What Does That Extra Power Mean for You?<\/h2>\n<ul>\n<li aria-level=\"1\">Lower energy bills \u2013 generate more of your own electricity and buy less from the grid\n<\/li>\n<li aria-level=\"1\">More energy for new tech \u2013 power an EV, heat pump, or home office\n<\/li>\n<li aria-level=\"1\">Increased savings \u2013 especially when paired with<a href=\"https:\/\/icerocketdesign.co.uk\/solar-pv-servicing-and-maintenance\/\"> solar battery storage\n<p><\/a><\/li>\n<li aria-level=\"1\">Opportunity to earn \u2013 excess energy can be sold back to the grid under the<a href=\"https:\/\/icerocketdesign.co.uk\/can-you-upgrade-existing-solar-panels\/\"> Smart Export Guarantee (SEG)<\/a><\/li>\n<\/ul>\n<p>If you\u2019re still on the Feed-in Tariff (FIT), you can keep your FIT payments while receiving SEG payments on any <i>additional<\/i> capacity you install.
